Details
The M3 Open Node can reset, debug and program the STM32 on JTAG through the FTDI4232H connected to the USB. This component allows also a UART link to the STM32. The Open Node connector gives access to 3 STM32/GPIO and the STM32/I2C. Two power lines are accessible on this connector:
- a + 5.0 volts for the board power supply
- a 3.3 volts for the consumption monitoring of the STM32, the RF component and the sensors
The M3 Open Node can be used standalone without a gateway connected to the M3 Open node connector. The powering of the board is then assumed by a battery or by the USB connector The choice of the power input is done electronically (power management).
