Product details

End-of-life — sourcing reality for the BOM line

Memory and I/O — sizing the firmware and the board

32 KB of Flash and 8 KB of RAM define the firmware footprint and data buffer ceiling. For a typical Modbus RTU gateway or a simple PID loop with a local display, that is enough headroom. The 28 GPIOs, combined with the serial peripherals, cover a moderate sensor array or a keypad-plus-LCD interface without an external port expander.

ADC and peripherals — analog input without an external converter

The 8-channel 10-bit ADC reads analog signals.
