The KISS V1.0 flight computer is TBNL Space’s first attempt at a single-board, SMF-component heavy pcb design and is currently in the late stages of manufacture!

KISS stands for Keep It Simple, Stupid, and represents the design philosophy for this design. While I did make the decision to move away from primarily using through-hole components for ease of manufacturing, I designed the schematic around simple circuits and known components.

The main processing and (local) communication will be handled by an Arduino ESP32, which will allow both real-time data processing and simulation, as well as local communication to ground stations and phone apps via Wi-Fi and BlueTooth.

KISS also features a secondary processor, the ATMEGA 2560-AUT. This processor is mainly used for I/O expansion, and communicates with the various sensors, external RF module, battery, servo motors, and 5 distinct current channels, including 2 parachute deployment lines and 3 external camera lines.

KISS supports up to 3 external camera modules, and optimistically aims to support streaming their feeds directly to connected devices on the ground for final vehicle checkouts.
