STM32L073RZ Nucleo-64 Development board with Program Cable

Description

STM32L073RZ Nucleo-64 Development board provides an affordable and flexible way for users to try out new concepts and build prototypes by choosing from the various combinations of performance and power consumption features, provided by the STM32 microcontroller. For the compatible boards, the external SMPS significantly reduces power consumption in Run mode.

The ARDUINO® Uno V3 connectivity support and the ST morpho headers allow the easy expansion of the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.

The STM32L073RZ Nucleo-64 board does not require any separate probe as it integrates the ST-LINK debugger/programmer.

The STM32L073RZ Nucleo-64 board comes with the STM32 comprehensive free software libraries and examples available with the STM32Cube MCU Package.

NodeMCU Development Board Pinout Configuration

Pin Category Name Description
Power Micro-USB, 3.3V, GND, Vin Micro-USB: NodeMCU can be powered through the USB port

 

3.3V: Regulated 3.3V can be supplied to this pin to power the board

 

GND: Ground pins

 

Vin: External Power Supply
Control Pins EN, RST The pin and the button resets the microcontroller
Analog Pin A0 Used to measure analog voltage in the range of 0-3.3V
GPIO Pins GPIO1 to GPIO16 NodeMCU has 16 general purpose input-output pins on its board
SPI Pins SD1, CMD, SD0, CLK NodeMCU has four pins available for SPI communication.
