RBpi zero w + Arduino Pro micro

Post by mrwhite81 » Fri Oct 12, 2018 6:21 am

I'll be keeping my simple Pro micro + cp2102 adapter for developing and bought new parts for the standalone build.
The parts I bought are:
Arduino Pro micro (Atmega32u4)
Link:

Raspberry pi Zero w
Link:

2 x Velleman metal film resistor ( 2.2K ohm and 3.3K ohm) 0,25W 1%
Link:
https://www.m.nu/motstand/metallfilmsmotstand-0-25w-1

When I'll be assembling it I don't trust my gewd old physics knowledge, or my interpretation of the forum posts / images. So to be sure, would someone please confirm / correct me on the ohms Law / flowchart.

I'm planning this:

(Soldering 1)
AVR Pro Micro RX (D1) -> RBpi UART TXD0 (GPIO 14) Pin 8

(Soldering 2)
AVR Pro Micro TX (D0)-> 2.2K Ohm resistor -> RBpi RXD0 (GPIO 15) Pin 10

(Soldering 3)
AVR Pro Micro Gnd -> RBpi Gnd Pin 6

(Soldering 4)
AVR Pro Micro Gnd -> 3.3K Ohm resistor -> RBpi RXD0 (GPIO 15) Pin 10

(Wiring)
USB Charger -> powerbank -> RBpi usb micro (Pwr)
AVR Pro Micro MicroUSB -> Console
