About the Rck22 PCB

Rck22 is an open source NXP PCB design by Muriukidavid, published on GitHub. It is a 2-layer board measuring 95.3 × 72.4 mm, with 75 components from 38 distinct parts.

Its main chip is the MK22FN512VLH12, from the NXP family. Other key parts include the PEC11L-4115F-S0020, XC6220B331MR, MAX31855KASA+T and N1616LCD_Shield. By type, the board carries 20 capacitors, 18 resistors, 10 connectors, 6 ICs, 5 diodes and 4 test points.

From the project

Design for a home toaster oven reflow based on tinyk22 module

This is a reflow oven controller based on tinyK22 board with NXP K22P121M120SF7RM MCU.

The goal is to use the board on a breadboard for developing the firmware and design a custom board

Rck22: common questions

What microcontroller does the Rck22 use?

The Rck22 is built around the MK22FN512VLH12, from the NXP family.

How big is the Rck22 PCB?

The Rck22 measures 95.3 × 72.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rck22?

75 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rck22 design files?

From the Muriukidavid/reflow_toaster_oven repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Rck22 design in my own project?

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

Can I test firmware for the Rck22 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
