A brain for my rocket

Features

• Arduino-compatible
• Adafruit Feather M0 firmware and pinout
• Small size - fits the smallest model rockets (e.g. 26mm diameter)
• Fairly powerful MCU (Atmel ARM M0 at 32MHz)
• GSM/GPRS for telemetry (SIM868)
• GPS for positioning (SIM868)
• 9-DOF Inertial Motion Unit (MPU-9259)
• Altimeter (BMP-280)
• MicroSD for logging
• Integrated usb-port, lipo-charger and power switch

Adafruit Feather compatibility

• Same pinout as Adafruit Feather M0. An on-board component interfers with D5 (see note).
• MicroSD wired similar to Adalogger M0, but chip-select is on D7 not D4
• Voltage is 3.0 instead of 3.3
• I2C pull-ups are present

Note: If you don't need hardware handshaking on the GSM UART, the D5 pin can be freed up by cutting JP2 on the back of the board.

Status

Testing in progress
