Swing and a miss…..
Real cute JV
$1 cheaper than ebay, but who wants the full-size USB connector? Aside from being archaic, they have a habit of shorting the base of any shield added.
The Geekcreit boards are pretty good. I'd suggest the Nano though, it's much smaller with the same hardware, although it does use USB Mini B :(.
Agreed, although I use the pro (no usb at all, but cheaper) and power using batteries - for usb powered devices I'd note being a fan of the Wemos D1R2 and smaller D1 mini. More memory, faster processor, and wifi built in. Can get the mini for around $4 delivered….
Needed if you have a CNC or RAMPS shield, though most people use a custom board now days.
Mostly I’ll prefer the wemos D1 or R32 modules.
Still cheap for the size, OP was correct.Never used the wemos specifically (it's ESP8266 based) but my board of choice is the newer, big brother to that the ESP32
Been meaning to try the ESP32 if only to get bluetooth and a few more gpio pins - for the moment the cheaper wemos mini has been more than enough for my purposes (mainly home assistant/esphome based sensors for temperature, motion, doors, etc) and I still have a few left in my parts bin since my last order. Will probably get some ESP32s when my stock runs out…. ;-)
@PlasticSpaceman: …and my giddy aunt, there are a few versions… http://esp32.net/#Hardware. I might try the Lolin D32 Pro V2 (https://www.aliexpress.com/item/32883116057.html) - looks pretty decent with built in ports for I2C, TFT, battery, sd card…
Maybe it could be used for playing Uno Attack (unfairly)?
