You may recall my blog entry about my “universal peripheral” – using the little Arduino Nano or similar clones with an ESP8266 – with the former providing GPIO via an I2c connection.
Well, that led me to getting this little number from Banggood – the Wemos Atmega + WiFi R2 Atmega2560+ESP8266 32Mb Memory board.
It’s not 32 MEG of course – it is 4MB – but that’s the same as a normal ESP12. but with the GPIO power of an Atmega 2560 – all in one neat board.
Initial impressions – it looks well put together. According to the underside, it takes DC 7-16v in – and has DC out at 5v 1.6A and 3.3v at 1 amp – so it actually is a little more than just the two boards – looks like there’s lots of power there for peripherals.
