Mini 35A 25S 4-in-1 ESC: For BLS U 35A V2.1 25S 4-in-1 electronic stability control system. Newly developed mini electronic stability controller for BLHELI_S 35A V2.1 4-in-1. High system integration in a significantly reduced standard size, with high performance and 5S support. Target: JH-25. Supports DSHOT, MULTISHOT, ONESHOT, and other protocols. The partially expanded pads save space and are durable. Uses an EFM8BB21F16G single-chip microcomputer with fast response. An increased capacitor helps reduce noise. Electronic stability control system with BLHELI_ firmware. Supports 25S voltage input and 4PWM input. Compact size: 31 31 mm; ultralight weight: 6.1 g. Supports ONESHOT125, ONESHOT42, MULTISHOT, DSHOT150, DSHOT300, and DSHOT600. Specifications: MCU: EFM8BB21F16G Ammeter: Yes Input: 25S LiPo Mounting holes: 20 20 mm, M2 Target: JH-25 Continuous current: 25 A Peak current: 35 A Size: 31 31 mm, including power pads Mounting hole spacing: 20 20 mm F3 integrated OSD mini flight controller: For SBUS and DSM receiver input, configure RX3 as the input interface. The DSM receiver is powered by 3.3 V. SBUS and PPM receivers use 5 V power. Factory firmware: Betaflight 3.1.0 for OMNIBUS. Equipped with an MPU6000 accelerometer and F3 flight controller for faster response; integrated 5 V 1 A BEC and OSD. This version is 6DOF and does not include a barometer or electronic compass. The board provides all functions while weighing only 7.7 g, with 20 mm mounting-hole spacing and M2.5 holes. Customized for quadcopter models, it includes an LC filter and supports Betaflight firmware. Uses an STM32F3CCT6 single-chip microcontroller with 256K flash memory and an MPU6000 sensor for the SPI interface. The source description ends here.
