It also has\u00a0the ICM42688P gyro, 4 available UART ports,\u00a0onboard 8MB blackbox, built-in barometer, OSD and\u00a0a 4-level battery voltage display. There&#8217;s\u00a0two independent voltage regulators,\u00a0a\u00a09V 3A output and 5V 2A output,\u00a0making it compatible with all DJI FPV air units and standard analog FPV.<\/p>\n<p>&nbsp;<\/p>\n<p>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&#8217;s, and configure other parameters without a laptop, simply via your phone or tablet wirelessly.<\/p>\n<p>&nbsp;<\/p>\n<p>The FC is compatible with a standard 20&#215;20 mounting pattern, using either M2 or M3 fixings, which are included. Considering the board&#8217;s small size, the size of the solder pads is generous and well labelled making for an easier installation.<\/p>\n<p>In stack form,\u00a0it comes with a 4-in-1 ESC that\u00a0provides four synchronized outputs with a continuous current of 35A and\u00a0burst of 45A. It\u00a0suits 3-6S input. It also has a current sensor allowing you to monitor power use.\u00a0Equipped with a TVS transient suppression diode onboard, it can better absorb the voltage spike when you plug in the battery, or during crashes that block your props. The ESC operates\u00a0BLHeli_S firmware and via the SpeedyBee App\u00a0you can even configure the ESC settings wirelessly as well.<\/p>","protected":false},"excerpt":{"rendered":"<p>Features: Compatible with both M2 and M3 installation hole sizes.
