Here's a similar, related project for an Arduino Pro Mini: https://www.openhardware.io/view/480/Compact-nRF24L01-Pro-Mini-Bottom-Shield

I also have project for mini.
The project have pads for battery, battery protection IC, LIPO charger USB for charging... battery voltage measurements....
But the project is not released yet, because high temperature during charging.

In the BACnet protocol, the messages are not sent directly, but pushed into an internal state machine that remembers (some) of the previously messages sent (i.e. memorize(_msg); send(_msg); ). The state machine also peeks incoming messages and can trigger a message re-send in case of a missed ACK. the difference with MySensors is that all the messages are numbered, otherwise you would not know which message of the last N sent previously was ACKed, but well.. ACKing the last similar message might be good enough. Anyway @SiLeX : if you want to try, this is not that complicated, (if you don't take into account the STREAMs) it will just costs about (1 status byte + 1 timestamp + 1 frame size) x N ; for N frames memorized.

@Alan-Minor said in Small nRF24L01+ Shield for ESP8266 Wemos D1 Mini: @NeverDie "Move" the trace to a different pin. AFAIK, yes.

@TommySharp Hmm dont really remember, but I think this was the solution https://github.com/knolleary/pubsubclient/issues/46

@TRS-80 There's an argument for putting two different value capacitors near the nRF24L01 (or whichever radio you're using). A 0.1uF bypass cap to help filter out noise, and a higher value cap as insurance against possible battery ESR and/or inductance from possible long battery leads/traces. For example: https://www.openhardware.io/view/480/Compact-nRF24L01-Pro-Mini-Bottom-Shield#tabs-design

Thanks for the tip!. It looks like a USB powered Arduino Nano cannot handle the long range radios power requirements. I powered the radio module independently and I can send commands succesfully again! The range has not improved, though, but that's another matter... Thanks !

Here is the code works with devDuino v2.2 It shows how all of the sensors on board (via com port) and also makes it possible to (expect) to download the firmware over the air.

Is this design for some existing enclosure?
