Two caveats: - Firmware is of an older version, and it produces warning during programming. Not a big deal - firmware can be updated, but it will be nice if it came with the current version pre-loaded. - This ISP downloader/programmer is a naked board. It feels flimsy/can be broken, and you might want to protect it by putting in a suitable box etc. Review: OLD Firmware. You need another AVR to upgrade firmware!!! - I was trying to download a new boot loader to my Arduino mega 2560 that somehow became corrupted. I downloaded and installed the drivers. Connected it to the header on the board. Went into the Arduino software, set the chip, board and com port. Hit download boot loader, and got an error. "cannot set sck period". I double checked my connections. re installed driver and tried again. -Same error. I did some research online, and come to find out the firmware is out of date on these!. So i started to look into upgrading the firmware. Here is where it makes the programmer useless, you have to have a working avr programmer to upgrade the firmware!!! If I had a working AVR programmer, I wouldn't need this one. DUH! So basically I just wasted $10 on this piece of crap. Hope this helps to keep others from making the same mistake I did. What a waste of time and money! ## Features - Powered by RioRand Advanced Technology - Onboard ATMega8 (L) chip - With power and program the two indicator - Onboard overcurrent protection - Support 5V and 3.3V power supply ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00N2FQ770 | | Customer Reviews | 3.5 3.5 out of 5 stars (13) | | Date First Available | August 27, 2014 | | Item Weight | 0.32 ounces | | Item model number | RR-US-BA-IS | | Manufacturer | RioRand | | Package Dimensions | 6.3 x 3.15 x 0.79 inches | ## Product Details - **Brand:** RioRand - **Manufacturer:** RioRand - **UPC:** 619636167645 ## Images ![RioRandUSB ASP ISP Downloader 51 AVR Programmer ATMega8 Support 5V 3.3V - Image 1](https://m.media-amazon.com/images/I/41IEx6oxkOL.jpg) ![RioRandUSB ASP ISP Downloader 51 AVR Programmer ATMega8 Support 5V 3.3V - Image 2](https://m.media-amazon.com/images/I/41UmbE08+JL.jpg) ![RioRandUSB ASP ISP Downloader 51 AVR Programmer ATMega8 Support 5V 3.3V - Image 3](https://m.media-amazon.com/images/I/41ijR0VZxhL.jpg) ![RioRandUSB ASP ISP Downloader 51 AVR Programmer ATMega8 Support 5V 3.3V - Image 4](https://m.media-amazon.com/images/I/41tGj9pCYwL.jpg) ![RioRandUSB ASP ISP Downloader 51 AVR Programmer ATMega8 Support 5V 3.3V - Image 5](https://m.media-amazon.com/images/I/51Tig2Q0ImL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ but it will be nice if it came with the current version pre-loaded *by T***Y on February 7, 2015* Works as advertised.

What a waste of time and money! ### ⭐⭐ I wish the outdated software had been indicated more clearly. *by U***K on June 8, 2015* This may well work okay. It has for some people. Like several others, I was not able to use it as it is, because of the outdated software and lack of a way to update it. So I found another way to program my ATtiny chips for the moment. One of these days, I might look for a way to update the software so I can try it out. I'd bet if one of the USB ASP ISP devices in the list were to have "updated/current software compatible with Windows, Mac, and Linux" in the description, they'd sell them by the buckets. But I dream of being rich, too. --- ## 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.com.pa/products/10144629-riorandusb-asp-isp-downloader-51-avr-programmer-atmega8-support-5v](https://www.desertcart.com.pa/products/10144629-riorandusb-asp-isp-downloader-51-avr-programmer-atmega8-support-5v) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-05-17*
