Within its smart shell, the device runs on ARM Cortex-M3 32 bit platform, provides basic waveform monitoring with extensive functions. It equips 320*240 color LCD, micro SD card storage, portable probes, LiPo Battery, USB connection and signal generator. Due to palm size and handy performance, it fits in-field diagnosis, quick measurement, hobbyist projects and wherever convenience matters. Scheme and source files are also open for re-innovating. Setup your SD card for first time usage: 1. Format SD card with FAT16. 2. Download Datafile. 3. Decompress it, and copy to the root folder of SD card. Notice: This is a NEW VERSION with the software upgrading from lib 2.25 to app2.6. ## Images ![RioRand (TM) Upgraded Pocket-Sized Digital Oscilloscope ARM DSO Nano RRDSO201 - Image 1](https://images-na.ssl-images-amazon.com/images/I/51qSXyowsjL.jpg) ![RioRand (TM) Upgraded Pocket-Sized Digital Oscilloscope ARM DSO Nano RRDSO201 - Image 2](https://images-na.ssl-images-amazon.com/images/I/51KWZ7KS%2B%2BL.jpg) ![RioRand (TM) Upgraded Pocket-Sized Digital Oscilloscope ARM DSO Nano RRDSO201 - Image 3](https://images-na.ssl-images-amazon.com/images/I/51syXysiT2L.jpg) ![RioRand (TM) Upgraded Pocket-Sized Digital Oscilloscope ARM DSO Nano RRDSO201 - Image 4](https://images-na.ssl-images-amazon.com/images/I/41%2B4SVIb29L.jpg) ![RioRand (TM) Upgraded Pocket-Sized Digital Oscilloscope ARM DSO Nano RRDSO201 - Image 5](https://images-na.ssl-images-amazon.com/images/I/41ahOYifG-L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ DSO Nano V1: Impressive little device *by S***D on Reviewed in the United States on December 2, 2012* The DSO Nano v1 is a basic one channel digital (storage) oscilloscope with a practical bandwidth of about 100kHz. To store data (images of the waveform measured) a basic micro-SD card (up to 2GB) is required. Comes with the v3.1 firmware. There are some problems (e.g. inaccurately displayed values) with the pre-programmed functions (V-max, Vp-p, etc.) depending on the voltage range and time resolution settings. The saved waveforms seem to be scaled correctly though and can be analyzed post measurement. The slowest time setting with this firmware is 2sec/div. The Nano is supposed to be firmware upgradeable with the BenF firmware (which apparently would fix most of the problems noted and also enable 10sec/div. However, all my attempts to upgrade the firmware (using a PC w/ Windows XP Professional/SP3) and the instructions on the seeedstudio forum were unsuccessful (the Nano would not go in the firmware upgrade mode when connected to the PC and turning it on while pressing the "-" or any other combination of keys.) Basically, the Nano just shows up as a drive. Even so, it works well enough as it is so - a solid 4 star.UPDATE 03/23/2013 (I): I have tried again to upgrade the firmware to BenF (see comments) and everything seemed to go okay until I restarted the unit, at which point it did display the BenF logo (see updated photo) but also it said that it could not find any app and it would just stay like that indefinitely. Thus, as of now, this, the latest of my attempts to update the firmware, essentially, seems to have rendered the device a total loss. Nevertheless, I'll keep the 4-star rating since the device was working okay before my messing with it.UPDATE 03/23/2013 (II): Looking around on the web I found what seems to be the latest (?) firmware from the manufacturer of my oscilloscope (Minidso). It is a (hex) file (the file is labeled DSO201 v3.3 but the actual firmware displayed on the device is v.3.03). Not really sure if this is the latest firmware since the "minidso" site is in Chinese so it's hard to tell. In addition, the original firmware on my Nano was labeled v.3.1. However, the new firmware undid the failed BenF stuff and the oscilloscope is working again (seemingly just as well as before - though I did not test it thoroughly nor did I try to calibrate it). In any case, reading through the posts on the "seeedstudio" forum, it appears that the only DSO Nano V1 devices that actually work with the BenF firmware are those from Seeedstudio. The other devices out there (such as this one) use a different USB bootloader (or something) and different firmware and may not be compatible (it most certainly does not work with the DFuse utility). I may try to update the firmware in the future, but for now I'm just glad the thing is working again. ### ⭐⭐⭐⭐⭐ wow very cool *by J***K on Reviewed in the United States on September 10, 2012* Came with version 3.01 software which seems to work very well, I was considering upgrading it with the BenF software but I don't see any need to and I don't think I could revert back to the original software if I did upgrade it. One note to make is to make sure you save your settings by pressing and holding the top run/stop key. When you save it, it will remember the settings the next time you turn on the scope. I have used oscilloscopes since the late 60's and this took a little getting used to. ### ⭐⭐⭐ Good value *by C***A on Reviewed in the United States on January 22, 2014* So, it's not the best scope in the world. Distorts at high frequencies, and, as I found out, doesn't accurately render low frequency signals. (i.e. a signal around 20Hz will show up with a wavelength that measures around 300Hz). But if you just want something that will show you what your waveform looks like, more or less, it's tiny, and its cheap. It doesn't come with a manual, but if you google the model number you can get the PDF. Operating it was a complete mystery until I figured that out. --- ## 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/4101557-riorand-tm-upgraded-pocket-sized-digital-oscilloscope-arm-dso-nano](https://www.desertcart.tn/products/4101557-riorand-tm-upgraded-pocket-sized-digital-oscilloscope-arm-dso-nano) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-27*
