RE3RT4Prog: common questions
What microcontroller does the RE3RT4Prog use?
The RE3RT4Prog is built around the PIC18F26K22-xSP, from the PIC family.
How big is the RE3RT4Prog PCB?
The RE3RT4Prog measures 130 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the RE3RT4Prog?
68 components, from 49 distinct parts. The full bill of materials is listed on this page.
Where can I download the RE3RT4Prog design files?
From the afiglee/RE3RT4Prog repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the RE3RT4Prog design in my own project?
The repository has no license, so all rights stay with afiglee. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the RE3RT4Prog without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
