BLHeli_32 is the 3rd generation ESC firmware after BLHeli and BLHeli_S, which is written for ESC's that utilize 32-bit MCU. With the increase in processing power, faster input signals with lower latency and higher update rate would be possible in BLHeli_32, such as Dshot1200!

PARTS UPDATED

F405 4S FC board has added extra 4 pluggable ports for ESC, VTX, RX and LED board, convenient installation and decreasing the dislocated PIN mounting.

Using single N-channel MosFETs on ESC board, which has a lower inner resistance. It is dual MosFETs on the original BLHeli_32 ESC board. Current sensor included.

BLHeli_32 ESC is soldering with 25V/220uf electrolytic capacitor, for reducing the defective rate caused by the instantaneous high voltage.

HOW TO ASSEMBLE FC & ESC

In order to be convenient for the installation and decrease the dislocated PIN mounting, we have added a port for ESC connection. Separate installation, in case the mutural vibration may interfere between FC and ESC.

HOW TO ASSEMBLE FC & LED BOARD

In order to be convenient for the installation, we have added a port for LED board connection.

RECOMMENDED RECEIVER CONNECTION

In order to be convenient for the installation, we have added a port for RX connection. All the ports are available on this board. So that you could connect any receiver you want on the board. For example.
