Hello,
I'm working on two projects, both of them with RFM and NRF option: what do you think? Are the PCBs correct?

1. First PCB
   

Hello,
this is a sensor with BME280, 0.96" OLED display and a custom PCB with Arduino Pro Mini 3,3v.
THe PCB is about 5cmx5cm with TP4056 LIPO charger, voltage regulator, space for an antenna, as described here: https://forum.mysensors.org/topic/5314/pcbs-for-battery-based-sensor

A button turns on the display:

Here the PCB:

Hello,
yesterday I added a 0,1uF capacitor between 3,3V and GND pins and I tried 8 different step-up booster without success!

In the next days I will try different configurations to understand what is happening!

@anticimex You are too fast :-) Now the CERN files are uploaded!!

2. PCB with SMD resistors and capacitors with LIPO module, arduino module and radio module

Hi,
the NRF24l01 doesn't have a RSSI function as reported in Nordic datasheet, so how can the signal report work?
thanks

thanks, next time I will use the github search function :-) :+1:
