Microcontroller | Option 1 | Option 2 | Option 3 |
|---|---|---|---|
Name | STSPIN32F0 | STM32L431 | STM32F051 |
Price/unit | $4.34 | $5.20 | $5.59 |
Pros | Integrated MCU with STM32F031, DC-DC, LDO, and gate driver for BLDC applications. Capable of FOC and Hall sensor feedback. Price can’t really be compared to other options. Physical size of ESC would be more compact since gate driver is integrated. | Existing design part of WARG, cheaper option | Used in previous ESC design from WARG, rated as “overkill” by others |
