SpeedyBee F7 Mini 20x20 Stack - Flight Controller & 35A ESC

PDF icon Manual2.38 MB

Here is a new FC / Flight Stack suited to 2-4inch quads from SpeedyBee. Like their other flight controllers, this one works with their fantastic SpeedyBee App (iOS App Store/Google Play); allowing you to configure your newly built quad, fine-tune PID's, and configure other parameters without a laptop, simply via your phone or tablet wirelessly.

The FC is compatible with a standard 20x20 mounting pattern, using either M2 or M3 fixings, which are included. Considering the board's small size, the size of the solder pads is generous and well labelled making for an easier installation. The spec of the FC is typical for a current flight controller, so it uses a F7 CPU, the MPU6000 gyro, includes OSD and on board blackbox. It also has two independent voltage regulators. A 9V 2A output and 5V 2A output, making it compatible with DJI FPV air units and standard analog FPV.

Speaking of the ESC, in stack form it comes with a 4-in-1 35A ESC with on board current sensor (it supports a 45A burst current). The ESC comes pre-flashed with Blue Jay firmware, which supports 48k/96k PWM frequency and Bidirectional Dshot. Via the SpeedyBee App, you can even configure the ESC settings wirelessly as well.
