Well, the company just sent me one of the new IOD-09 displays and it is the cutest thing you’ve ever seen.
You will possibly be familiar with the little OLED displays I use a lot from the likes of AliExpress and Banggood (or Ebay for that matter) – the SSD1306 based units. They are amazingly small – but if course you then need a Nano or ESP8266 to drive them – boards invariably larger than the display by some way.
Well, IOD-Systems IOD-09 is TINY – only a little larger than the SSD1306 really…
0.9” – 80px by 160px full colour with WIFI… at $19.95 it isn’t cheap but it is LOVELY – unlike the SSD1306 which is a PART and a pain to get a bezel for, the front of this is a nice black rectangle – ready to fit into a suitably sized front panel hole. You can program it with Arduino Core or 4D Systems own software.
Amazingly they’ve also fitted into almost no space under the board, a microSD socket. 12 pads, 6 on each end for connecting to accessories. About the only thing I could think of to gripe about is the 4Mb of FLASH (512K) which makes OTA somewhat difficult. I do wish people would stick with 4MB.
The board operates on 4v to 5v and my TH version is 31.8mm by 16.4mm by 11.7mm – there is an SM version at 37.0mm by 16.4mm by 5.9mm – here’s the datasheet.
