Review on π‘ HiLetgo UNO R3 WiFi ATmega328P + ESP8266 NodeMCU 32MB Memory USB-TTL CH340G for Arduino | Includes USB Cable & 2.4G WiFi Antenna by Dusty Oner
Resold Returning computer components
Looks like someone previously bought the exact device I received and returned it. How do I know? Because you can see that someone uploaded the popular "flashing" sketch (one second on/off "L" LED). Somehow they screwed up with the device, called it bad and returned it with a refund. I highly doubt that HiLetGo will ship the device with the thumbnail already loaded. Either way poor quality control. I don't expect to buy another device because of this. Very cool concept of two useful circuits on one board. I was never able to verify whether 32 MB is on board, as stated in the description.
- Power supply voltage: 6~9V; Microcontroller: ATmega328; USB Driver: CH340G
