About the Programmer PCB

Programmer is an open source PCB design by finnhittson, published on GitHub. It is a 4-layer board measuring 54.1 × 43.8 mm, with 15 components from 11 distinct parts.

Other key parts include the LM2937xT. By type, the board carries 5 resistors, 2 connectors, 2 diodes, 2 capacitors, 1 IC and 1 transistor.

It belongs with the robotics & motion, power & battery and usb & debug tools designs in this gallery.

Because this project is intended to be a workshop only one version of code or main.c file is written for simplicity. Therefore, for the main.c to differentiate between running transmitter code and receiver, a GPIO pin on the micro is dedicated for this indication. The pin under questions is RA5 (pin 2) from the tables below which descripe the pinout for the PIC16 in both the receiver and transmitter. If RA5 is pulled high, then the main.c executes transmitter code only. Similarly if RA5 is pulled low, then the main.c only executes receiver code.

Programmer: common questions

How big is the Programmer PCB?

The Programmer measures 54.1 × 43.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Programmer?

15 components, from 11 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Programmer design files?

From the finnhittson/RC-Car-Build-Workshop repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Programmer design in my own project?

The repository has no license, so all rights stay with finnhittson. Use it as a reference, and ask the author before reusing the design.
