A-Star 32U4 Mini SV (ac02c)
This original ac02c version of the A-Star 32U4 Mini SV is a programmable module based on the ATmega32U4 from Microchip (formerly Atmel) and featuring an on-board switching step-down regulator that allows it to be powered efficiently from a 5 V to 36 V supply. This product has been replaced by a newer ac02f version with an improved regulator that operates up to 40 V and can deliver more current.

- Without included optional headers. This measurement includes the USB Micro-B connector, which extends 0.05″ past the edge of the PCB.
- Without included optional headers.
- Note that 4 KB of the MCU's 32 KB of flash memory is used by the pre-installed USB bootloader. All 32 KB is available when programming via the ISP header rather than the bootloader.
- For light loads. The regulator's dropout voltage increases approximately linearly with the load, from a few millivolts at no load up to around 0.6 V at 500 mA.
- Available current depends on input voltage, current consumed by the board, ambient conditions, and regulator topology. See product documentation and performance graphs for details.
- On Bat+ (LV, SV) or Bat- (ULV).
