Mumbai (CAN Rocket Avionics)
Project Mumbai is our CAN-based rocket avionics PCB stack for competition.
The boards all include similar parts to aid in quick design and to increase modularity:
- MCP2562 transceiver chip to interface with CAN bus
- STM32 microcontrollers (F103 variant at this point but this could change in the future)
- Capacitors, resistors, and LED's of the same physical size
The general restock BOM can be found here: TO BE COMPLETED
The CAN-Based system consists of the following SRAD printed circuit boards:
- Flight Computer Board
- Recovery Board
- Data Logger Board
- LoRa Radio Board
- Power Distribution Board
- Battery Board
- GPS Board
- Temperature Array Board
- Sensor Board
The Hybrid rocket will add the following boards to the CAN-Based system: TO BE COMPLETED
- Vent Board
- Injector Board
- ????????
The system also features the following COTS boards for redundancy:
- EasyMini Flight Computer
- BigRedBee GPS Transmitter
- North Star Systems Payload Board
The flight computer board is the brains of the system. It takes in data and makes flight critical decisions like when to deploy the parachute.
The recovery board will include a modular deployment system. This consists of being able to easily switch between a burn wire, pyrotechnic, or CO2 canister type of deployment system.
Our data logger board will feature an micro-sd card for quickly gathering data when troubleshooting and be capable of storing 100x more data to FRAM than our mini rocket board allowing for a reliable storage method in flight.
Our first revision of our radio board will consist of an RFM96W LoRa Chip. It will be able to take data from CAN-Bus, interpret what data to send over radio, and send that data over 10 km.

Preliminary design has been completed, basing off designs from Andoya Space (see below)
The sensor board contains 100+ payload sensors for the rocket.
