Hi guys, this is my firs post here, so thank you for the amazing work!
I'm working on a multisensor (3 x Pir, 1 x DHT22, 1 x LDR, 1 x OLED display, 1 x WS2812B led ring for signaling and as small RGB lamp, 1 capacitive touch button) with an arduino pro mini 3.3V (8 Mhz) and NRF24L01+, all placed in a hexagonal custom case (3d printable).
The sensors has also a TP4056, a 18650 Li-Ion battery and a step-up boost converter to power the arduino (raw pin) and all the other components. The radio is powered through the arduino Vcc Pin (3.3 V) and all works quite good on a breadboard.
Now I'm in the soldering phase (perfboard) but this task is very time consuming and this technique gives a "non professional" looking to the inside of the node, so I have found this easy-newbie pcb and it is great! Thank you for sharing this!
So my plan is to use this pcb instead of three different perfboard but I think that at the moment the power section is not fully compatible with my setup, but with some modification it will be OK and this modifications could allows more flexibility in the power options for the pcb.
Off course I don't have the skills to directly design and share a modified pcb, so I'm writing here my idea with the hope that, if it is useful, someone can implement it.
Here is the schematic of the modified power section.
I think that, with this schematics and the appropriate hardware choice, it is possible to cover a large number of power supply options (regulated and unregulated power input, 5V and 3.3V pro mini, 2xAA battery, 12Vin, 24Vin, 9V battery, TP4056 + 18650 Li-Ion cell, daughter board power source, etc...) , simply changing a couple of jumpers.
About daughter board... I don't know which is the best connection option for the Vraw pin of the MysX connector... Raw or Vin? Maybe Vin...
Let me know what you think and if it can be useful. Sorry for the long post and bad english.
