Interactive Pinout

See https://github.com/mck1117/wideband

See rusEFI forum: F103 dual channel wideband controller + EGT + 2 x AUX In + 2 Aux out

  • STM32F103 dual channel wideband AFR controller supporting Bosch LSU4.9 (LSU4.2 and LSU_ADV work in progress)
  • CAN and analog output
  • x2 EGT input using MAX31855KASA or MAX31856
  • x2 auxilary analog input: 0..5V with pull-up or pull-down (configurable by soldering resistor). One can be used to source 5V to external sensor.
  • x2 2 auxilary output 0..5V. Also can be used for slow PWM signal output.
  • x2 open drain outputs: BTS3028 (5A)
  • Bluetooth TunerStudio connectivity

Changelog

rev 1

  • Switch to 64 pin STM32/GD32
  • Add 8MHz HSE oscillator (better clock stability for CAN over wide temperature range)
  • Use DAC (instead of PWM) outputs for driving Ip
  • Move BT to UART3/USART3, keep USART1 for bootloader/debug
  • Drive BT's EN signal from MCU
  • Fix RC filters on heater outputs for better voltage measurement
  • Use separate ADC input for Vbat measurement
  • Use ADC channels for AUX outputs monitoring/diagnostic
  • Use PWM noise cancelation circuit on AUX analog outputs
  • Removed useless/non-functional protection of Vm outputs
  • Fix board outline to fit two types of enclosure ("plastic top" and "alloy brick")
  • Add testpoints for TC2030 JTAG probe
  • Add buttons for Reset and Boot0
  • Add Cfg1 and jumpers
  • Replace fuse holder with resettable 0.2A 33V fuse
  • Two status LEDs for separate status indication for left and right channel
  • Silkscreen labels around testpoints
  • Silkscreen labels at uart connector on both sides of PCB
  • Un_3x_sense formula is now 0.247 + 3.15 * (Un - Vm)
  • Un_sense (not gained) is also routed to ADC input
  • Protection from possible Ip current when MCU in reset/bootloader
  • White "power on" LED replaced with green
  • Main connector pinout added to top silkscreen
  • AUX connector pinout added to top silkscreen
