STAG AFR - another cheap WBO2 controler

Post by JRD McLAREN »

I have STAG AFR module on my board .. (not in car yet)
It is wbo2 controller for Bosch LSU4.9 sensors
Has serial output, two analog 0-1V for narowband and 0-5 for wideband.
Also has narowband emulator.

It has STM8AF6288TC MCU
two MCP604E OP-Amps
two LM2903Y comparators
VN5025AJ highside power switch as heater driver

STAG provide they own application
- AC-AFR for windows
- AFR Mobile for android

Can be connected via TTL serial port or Bluetooth.
Serial speed is 57600,8n1
(my favorite HC-05 work)
