Based on ST SPIN Series Low Voltage Fan Solution
Integrated three-phase half-bridge driver, Hall cordic, op-amp, comparator, BUCK, LDO, MCU Soc, due to the small size, low comprehensive BOM cost, without too many peripheral devices, very suitable for low-voltage motor control.
This development board to achieve single-resistance sampling non-inductive motor control, Hall / magnetic feedback motor control, applicable to the application of 24V low-voltage motor fan, water pump, and power tools;
The main chip uses STSPIN32F0A, the MOS uses 6 STD140N6F7, the maximum power can reach 360W;
Development board integrated with STLINK/V2, convenient for debugging;
The official firmware library provides FOC algorithm and BLDC algorithm, which can be fast and portable for customer research and development.
