VCC or 3V3 output (depending on your specific chip) to the VCC pin of U2 and PC10 pin of U1. This will provide power to your entire circuit. Do check however if both components support the same voltage levels.GND from the USB-C to UART bridge to the GND pins on both U1 and U2.TX pin from the converter to the RXD1 (receiver) pin of U2 and PD8 pin of U1.RX pin from the converter to the TXD1 (transmitter) pin of U2 and PD9 pin of U1.IC1 TXD (pin 1) to U1 PD9 (pin 191). This will allow IC1 (FT232) to transmit to U1 (STM32).IC1 RXD (pin 5) to U1 PD8 (pin 192). This will allow U1 (STM32) to transmit to IC1 (FT232).IC1 VCC (pin 4) to the power net supplying 3.3V or 5V, depending on your board's requirements.IC1 GND (pins 7, 18, and 21) to the ground net of your circuit.IC1 USBD+ (pin 15) and IC1 USBD- (pin 16) to the D+ and D- pins of your USB interface (e.g. USB jack or USB cable).IC2 SDA (Pin 24) to U1 PB9 (Pin 223). This is for the I2C data line.IC2 SCL (Pin 23) to U1 PB8 (Pin 224). This is for the I2C clock line.IC2 VDD (Pin 13) to a 3.3V power source.IC2 GND (Pin 18) to the ground net in your circuit.IC2 INT (Pin 12) to an available interrupt pin on the STM32, for example U1 PG8 (Pin 88).IC1 (FT232RL-REEL) and J1U2 (NEO-6M-GPS) and U1 (STM32H743XIH6)J1 and IC1 (FT232RL-REEL)Reviews
