Is module with: ESP8285 (ESP8266), 50 kB RAM, 1 MB Flash

I think I would prefer a TTGO Micro-32 - ESP32-Pico-D4 module instead:

Module with: ESP32 Pico, 2 cores, 520 kB RAM, 4 MB Flash

true more power in a little box.

but its something I want to try… receiving TTN MQTT over wifi in a little client… how… don’t know yet but we need small displays and wifi :sunglasses:

almost forgot this :crazy_face: … well the parts are coming in … ZzzzZZZzzzzz lowly.

Interesting design in both hard- and software. Still many questions about the design considerations.
