Firmware Release V0.0.3

V0.0.3 firmware release. Includes App and Bootloader HEX assets. App adds the output V/I calibration workflow while keeping the release safety limits: 2200 V, 200 mA, 400 W, OCP 60 A, OTP 70 C, and internal supply UVLO/OVP. Calibration is disabled by default and flash writes are locked while output is enabled.

Firmware Release V0.0.2

Public App firmware V0.0.2.

• App firmware only; Bootloader is not included in this release.
• Adds internal lower-MCU UVLO/OVP gate inhibit: VPRI OVP >32 V, AUX12 8-15 V, AUX5 3.7-6.5 V, MCU/VREF 3.3 V window 2.7-4.2 V.
• Protection trips after 30 switching periods of filtered abnormal supply values and auto-recovers after 10 normal periods; host protocol state and software enable remain compatible.
• Built with Keil MDK locally: 0 Error(s), 0 Warning(s).

Firmware Release V0.0.1

Public firmware V0.0.1.

• App firmware limits: CV 0-2200 V, CC 0-200 mA, CP 0-400 W.
