PID Toaster: common questions
What microcontroller does the PID Toaster use?
The PID Toaster is built around the TPS61222DCK, from the RP2040/RP2350 family.
How big is the PID Toaster PCB?
The PID Toaster measures 119.8 × 126 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PID Toaster?
105 components, from 52 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 PID Toaster design files?
From the benkyd/benhardware 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 PID Toaster design in my own project?
The repository has no license, so all rights stay with benkyd. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PID Toaster without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
