@berkseo please stop spreading everyones efforts all over the forum. What happens if someone answers you here, someone else answers in another of your identical posts and a third person answers in yet another thread? everyone will be confused, information will be spread all over the place.

@mfalkvidd
This is odd... The developer of this device may not see my question in other forum topics. Here I asked him, I'm interested in his experience and opinion. But okay.

@berkseo then create a thread, and reference the thread everywhere you ask so we can collect everyone’s time and knowledge about your problem in one place.

After testing the board for a few weeks I implemented a major redesign, marked as V4. Not tested yet.
Changes:
- Changed headers to XH2.54 connectors for leds and buttons
- Added secondary regulator to power RF modules
- Changed RFM69 footprints to remove unused pads
- Changed CHG340G chip to CHG340C, eliminating the crystal
- Relayed all traces for cleaner design
- Added capacitors at USB input power
- Added second capacitor for decoupling at RFM69 modules

Version 4.2 was just published. The board now also contains breakout headers for I2C devices (temperature sensors such as Si7021, HTU21D, SHTT71 and BME280) and a headers for a RXB6 RF 433Mhz receiver. Not tested yet.
