STM32L476G-EVAL  

The STM32L476G-EVAL evaluation board has been designed as a complete demonstration and development platform for STMicroelectronics ARM® Cortex®-M4 core-based STM32L476ZGT6 microcontroller with three I^²C buses, three SPI interfaces, six USART ports, CAN port, SWPMI, two SAI ports, 12-bit ADC, 12-bit DAC, LCD driver, internal 128-Kbyte SRAM and 1-Mbyte Flash memory, Quad-SPI port, touch-sensing capability, USB OTG FS port, LCD controller, Flexible Memory Controller (FMC), JTAG debugging support.

The full range of hardware features on the board helps user to evaluate all the peripherals (USB OTG FS, USART, digital microphones, ADC and DAC, dot-matrix TFT LCD, LCD glass module, IrDA (supported up to version MB1144 C-01 of the board), LDR, SRAM, NOR Flash memory device, Quad-SPI Flash memory device, microSD^™card, sigma-delta modulators, smartcard with SWP, CAN transceiver, I^²C, EEPROM, RF-EEPROM) and develop applications. Extension headers allow easy connection of a daughterboard or wrapping board for a specific application.

An ST-LINK/V2-1 is integrated on the board, as embedded in-circuit debugger and programmer for the STM32 MCU and the USB virtual COM port bridge.
