It supports global LTE Cat-M1 and NB-IoT cellular connectivity, solar charging, and a wide range of peripheral interfaces, making it ideal for professional-grade IoT projects requiring reliable, low-power, and worldwide communication capabilities. ## Description Product description Product Description Power Antenna Shipping List The battery's positive and negative poles are connected to the wrong protection, overcharge and over discharge protection GPS power control, reduce power consumption, the lowest reaches 300uA when sleeping Replacement of ordinary charging IC with solar charging IC Added active GPS antenna power control, when the module GPIO4 is not turned on the antenna consumes only the static current of the LDO Github ：github.com/Xinyuan-LilyGO/LilyGO-T-SIM7000G Product Pin In the pin diagram, the red indicator light near the upper right of the switch is only on when the battery is connected, and it is always on when the USB is connected. It indicates that the battery is charging. If the battery is not connected, it may be Flashing. Below the red light is the green indicator light, which lights up only when the battery is fully charged, and it is always on when the battery is connected. Close to the side of the SIM7000G antenna is the status indicator. If the SIM7000G starts normally, it will always be on. If it does not start normally, it will not be on. It cannot be turned off by software. Close to the status indicator is the network indicator, it indicates the network status, it can be closed by software. SIM7000G does not support 4G network . Please ensure that the USIM card you use supports 2G(GSM)/NB-IOT access. pin VIN is a USB input, if a battery is being used to power the device there will be no voltage output from VIN meaning 3.3v is the only power output. When using the built-in battery pack the on/off switch will function as normal, supplying/cutting off power to the board, However, if an external battery pack is used and attached to the VBAT pin the on/off switch will be bypassed meaning the only way to shut off will be to disconnect the batteries. On/off switch is for battery use only, it will not function when plugged into USB. Battery voltage can not be read when plugged into USB using the onboard BAT ADC(35) Recommended solar panels are 4.4v to 6v DO NOT EXCEED OR BOARD MAY BE DAMAGED SHIPPING LIST 1x T-SIM7000G 1x SIM antenna 1x GPS antenna 1x Power cable 2x Pin Review: Decent IoT device. Works as advertised and...heh...more... - Let's get one detail straight. The vendor claims that it doesn't work with LTE networks. This is...misleading. If you're talking 4G and 5G? YEAH. It's not capable of anything other than IoT-NB, Cat-M1 (Hint...), and GSM (2G, largely shut down...) for it's connectivity. It's not fast, nor is it intended to be. If your provider does IoT-NB service, this will work nicely. If your provide does LTE Cat-M1 (M2M, narrowband service), it will work nicely as well. The statement that it does not do LTE needs to be dropped by LillyGo- it causes them a problem. It means people won't use their product with a KORE SuperSIM. Which you should rather very much DO. It's using a SIM7000G, _Global_ modem. Works largely worldwide- paired with a KORE SuperSIM, you can have your IOT device work just about anywhere there's, "M2M Cell Service." One proviso. It doesn't do IoT-NB service, the competing answer. If you have one of those providers and an IoT-NB SIM go right on ahead. If you were going to use KORE's SuperSIM or something like Verizon as your provider, go right on ahead with confidence. As long as their M2M service uses Iot-NB OR LTE Cat-M1, you can use this product for your project. That handled and done, how is this as a device. If you can handle the bit of Chonky length introduced by their choice of a 18650 class Lithium rechargeable cell, there's little to NOT like there. ESP32. Development is possible with Arduino, PlatformIO, MicroPython, and more. Fairly high performance dual core microcontroller with 2.5 GHz WiFi, Bluetooth, decent SPI/I2C/GPIO support. Does LTE-M1 data sensibly and...fairly easily...all things considered. SMS is _possible_ but requires your provider _provisioning_ this for you in your SIM for the unit. (Need to have a convo with KORE/Twilio people about the SuperSIM...need SMS directly that simply goes to 1-3 locations, mostly delivering a message to the deistred number as a Mission Critical aspect. Internet's not reliable for this...) Deep Sleep capabilities. Competing devices don't do this right now due to COVID induced supply chain problems. Only real drawback is that, like MOST of the actual plays in IoT, it's less "novice friendly" and has somewhat less than stellar documentation overall- but you'll find yourself thanking yourself down the line for it. It's looking like a solid performer overall to my project- prototype will be able to be done...now that I figured out how the LTE modem actually worked within the device- which is a bit counterintuitive for modems up the Foodchain in the 4G/5G space. Review: Worked Perfectly First Time! - First let's get this out of the way. I'm surprised these people don't know their own product. It connects via 4G! This is from the Device I connected 10 minutes ago: +CPSI: LTE CAT-M1,Online,310-410,0x4C0E,182550289,215,EUTRAN-BAND12,5110,3,3,0,0,125,7 It's CAT-M1. So the 2G statement is just flat out wrong. Now onto the good stuff. Once I got the board fired up, I did these steps and was running in less than 30m. I'm adding the time took. Chat GPT was mostly helpful. 1. Connect antennas 2m (they actually are quite hard to press in) 2. Install ESP32 board drivers through Arduino 5m 3. Install battery - 10m. I had to bend in the tabs with needlenose pliers as the battery simply would not fit. 3. Bring in all functions example from Github and compile 5m - no issues! I ran my sim broadband so the APN stuff wasn't even necessary. i used 'broadband' for APN. 4. Upload and run 10m You have to slow down the upload speed, or at least I did have to reduce it from 900k to 500k. This is in Arduino Tools->Upload speed 5. Open serial port and run - 10m 6. Post data to cloud - 60m I could not find 6 to send data. in all functions so I added an http get and used dweet.io which is a very skinny method to display device data from cloud side. Take a little time to learn the AT commands. I can't say enough about this board. It connected with default settings to AT&T and displayed device data on dweet.io. GPS works, everything just works. Finally one last compliment it has a great build quality and is quite stout! ## Features - 16MB Flash and 8M PSRAM - Note：SIM7000G does not support 4G network.

I got this to setup a gps tracker for my parents camper. I can send an email to the board with a phone number and it will start sending the coordinates every hour. I can stop it remotely. And there is a distress button I wired up to send an sos and coordinates to selected phone numbers. I plan to add more features when they're back from their first trip. ## Frequently Bought Together - LILYGO T-SIM7000G ESP32-WROVER-B Solar Charge SIM GPS Antenna CH9102F 16MB 2G/NB TTGO Development Board - Soracom Air Global Plan01s IoT SIM Card Secure Cellular Connectivity SIM Card for IoT M2M Projects Pay as You Go No Contract (1-Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/356009846-t-sim7000g-esp32-wrover-b-solar-charge-sim-gps-antenna](https://www.desertcart.tn/products/356009846-t-sim7000g-esp32-wrover-b-solar-charge-sim-gps-antenna) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
