I drew the PCB – using CADSoft Eagle – for it was possible to made it with hobbistic methods:
- all the components have through-hole packages;
- it is single-sided (= all signals are routed on the bottom layer);
- minimum track width is 15mil.
After having made the PCB (at home or using an external service – for this project I tested OSHPark I’m going to review in a coming post), solder the components starting as usual from the smallest ones (resistors, capacitors…).
Download from Github’s repository the firmware Type4me.hex.
Connect your PIC programmer to the ICSP connector – please make sure Type4me is not connected to the USB port – and program the firmware:
