F4 Brushless Flight Controller and ESC V2.0 (BLHeli_32)
After several months of research, the greatest combination of F405 4S Brushless Flight Controller with BLHeli_32 16A ESC has been released which totally supports 4S power with a steady performance. BLHeli_32 16A ESC is customized for Beta85X whoop drone. Meanwhile, Beta85X is the first micro drone with a BLHeli_32 ESC at present. 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! Know more about BLHeli_32 ESC from Oscarliang's blog. Check out Joshua Bardwell's video to know every detail of BLHeli_32 SPECIFICATIONS OF FC CPU: STM32F405 (Overclock to 240MHz) Six-Axis: MPU6000 Size: 26mm x 26mm, whoop mounting pattern Firmware version: BETAFPVF405 (BEFH) OSD: Built-in BetaFlight OSD (STM32 controls OSD chip over SPI in DMA mode) RX3 and TX3 are with auto inverter, supporting all RX including TBS Micro RX TX01 and RX01 ports are available for Frsky F-Port, DSM2/DSMX Buzzer solder pads Support programable LED like WS2812 etc Weight: 4.2g DIAGRAM FOR F405 4S FC SPECIFICATIONS OF ESC Support BLHELI_32 Support PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300, Dshot600, Dshot1200 Input voltage: 3-4S lipo Cotinue current: 16A Peak current: 19A Firmware target: BETAFPV-16A-32bit MCU: STM32F051K66 Motor Connectors: 1.25mm header pins connector Weight: 4.4g (7.7g with XT30 cable) DIAGRAM FOR F405 4S FC 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. Frsky XM/XM+ Receiver Flysky Receiver TBS receiver DSMX receiver Here is the connection diagram with Frsky XM receiver or XM+ receiver Here is the connection diagram with Flysky receiver. Here is the connection diagram with Futabe-X-BOSS AC900 receiver. Here is the connection diagram with TBS Crossfire receiver. Here is the connection diagram with DSMX FullSpeed receiver.
