The Rockit (rocket operation computing kit) is an affordable flight computer designed for small model rockets. You can even use the board with water rockets since it’s so small and lightweight! The board features an RP2040 dual-core microcontroller, altimeter, accelerometer, and data logging via a microSD card. You also have power management for controlling two servo motors. And all that weighs in at a mere 5 grams.
The board measures 44 × 22 × 9 mm. I typically don’t give dimensions of products in these reviews, but when you’re talking rockets, size matters! The board comes fully assembled and tested and includes header pins if you want to solder them on for added functionality, but that’s optional. Just add a microSD card and AAA battery pack with a JST connector and get to coding.
