MotoLab Cyclone STM32F3 Flight Controller

The Cyclone uses the STM32F3 CPU withARM-Cortex M4 core and floating-point coprocessor for more efficient execution of fast looptime control algorithms, along with the low-noise MPU-6000 SPI-bus gyro chip for faster acquisition of gyro data. This board is compatible with the recent revisions of Betaflight firmware, using the betaflight_MOTOLAB target files. The PWM outputs are bidirectional, and the board is compatible with BLHeli ESC passthrough programming using an external CP2102 USB-to-serial converter connected to UART 1. The design also provides: An on-board 600mA switching regulator for direct connection to lipos up to 4S, or up to 6S with power filtering. USB interface independent of UART channels. Three hardware UARTs. The UART 2 TxD signal is also pinned out to a connector. Reverse current protection on lipo and USB inputs for problem-free ESC calibration. Dedicated serial LED output with lipo voltage and GND. On-board buzzer driver with 5V and lipo voltage option. Built-in VBAT monitor with low-pass filter from lipo input. Built-in RSSI monitor with low-pass filter. Dedicated SAT receiver interface with 3.3v using JST connector for compatibility with Spektrum/LemonRC cables. Dedicated PPM and serial receiver interfaces with 5V power using 0.1" headers. Compatibility with receivers using Spektrum 1024/2048, SBUS, SumD and SumH receivers with built-in inverter. High-quality gold plated 4-layer printed circuit board. Connector arrangement for convenient access to serial interfaces, with PWM and other device connections on sturdy through-hole pin headers.
