Compact sensor integration
The 45.0 × 45.9 mm board carries ICM-45686 and BMI088 inertial sensors, a BMP390 barometer and a BMM350 magnetometer. The processor includes 1 MB of RAM and 4 MB of in-package flash.
UKK-1
528 MHz flight-control hardware on a 45 × 45.9 mm board.
UKK-1 integrates an i.MX RT1064 Cortex-M7 rated up to 528 MHz, dual IMUs, a barometer and a magnetometer on a six-layer PCB. Eight PWM signal outputs, CAN and 100BASE-T1 Ethernet sit alongside GPS, telemetry, USB-C and microSD connections. Protected input and current-limited peripheral supplies are built into the board.

Hardware features
CAN and single-pair Ethernet
A dedicated CAN transceiver and 100BASE-T1 Ethernet PHY provide wired connections alongside two telemetry UARTs and an auxiliary UART. Ethernet requires a compatible 100BASE-T1 peer or converter.
Protected power distribution
The power input includes reverse-polarity and over/undervoltage protection. Current-limited peripheral and GPS supplies, a 3.3 V buck regulator and reset supervision are integrated into the design.
