HappyModel Diamond F4 5in1 1s Brushless Flight Controller - FrSky Version

Ultra-light 1S all-in-one flight controller with switchable VTX power output, 5A ESC and supporting FrSKY D8/D16 protocol. To save weight, HappyModel decided to go with direct motor soldering instead of the connector seen on previous boards.

Notes: DO NOT FLASH THE BOARD WITH 4.3.1. There are SPI related issues when using 4.3.1. A fix is coming with a new firmware that will be available soon (4.3.2). STAY ON 4.3.0 OR BELOW.
Although D8 is still recomended, if using BF 4.3.0, you can now use D16 as well.
