@bluejedi … that would make a nice small 1.54 e paper mqqt ttn client
not bad … normally I never win
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
almost forgot this … well the parts are coming in … ZzzzZZZzzzzz lowly.

IP65 Ethernet connector

Interesting design in both hard- and software. Still many questions about the design considerations.
what’s 'onboard ? 328p / rfm95w / 3v3 dc dc /bme 280 . just guessing
yes, yes, yes, yes. GPS is not connected.
I think it’s an FPGA with 256M gates.
(Sensors to be added on the left.)
its an PE1duino … probably with CH2i lowpowuRrrrrrr
