Loading 3D model… large boards can take a moment.
The D23 decoder is a double sided mobile decoder with 8-pol NEM 652 connector. The decoder is designed to integrate into the RTB digital control infrastructure.
The current PCB layout uses SMD footprints with 0.5mm pitch and 0402 parts. Reflow soldering is mandatory whereas handsoldering near to impossible.
:yellow_circle: Requires my Kicad project library RTB_SamacSys in the same directory tree.
Filename structure: { pcb }{ code }{ version }.hex

| Description | |
|---|---|
| pcb | Name of matching hardware (D23) |
| code | Type of code contained (R=rom, B=bootloader, F=flash, U=bld update, P=UPDI factory code) |
| version | Release version (####) |
The fuse settings as well as the P-code (D23Pxxxx.hex) has to be installed by using UPDI.
Connecting the decoder via its track pins to a 5V(DC) power supply will boot its CPU. This way, its easy to program the fuses and flash.
