Description Adafruit METRO Development board with tube holder - ATmega328 Adafruit METRO is a derivative of Arduino UNO board (RS 769-7409), so you can find a large number of projects and sample codes for use and adjustment. Using 32 KB flash memory and 2 KB RAM to run ATmega328P at 16 MHz is very suitable for most simple projects. There are a total of 19 GPIO pins, including analog input, hardware UART, SPI and I ² C, timer, and PWM. The logic level is 5 V, but this level can be easily converted to 3.3 V. The socket is assembled and welded, and the board has undergone comprehensive testing. You can use a 7 V DC or 9 V DC PSU to power METRO through a 2.1 mm DC jack with an on/off switch nearby. In addition, you can use a 5V micro USB connector to power it. METRO can automatically switch between USB and DC power. Compatible with all Adafruit shields and stackable directly to the top to add specific features. Metro displays through a connected 12 button capacitive touch extension board to demonstrate how to work with the shield (not included). Four LED indicator lights are located at the front edge of the panel, making it easy to debug even if the expansion board is at the top. For projects where board size is crucial, a reduced version of METRO Mini board (RS 124-5512) is available for you to choose from. \-ATmega328 microcontroller with Optiboot (UNO) boot loader \ - USB programming and debugging through fully supported original FTDI FT231X \ - Input voltage: 7 V DC to 9 V DC (recommended 9 V DC power supply) \ -5V regulator can provide peak~800 mA, provided that the regulator's chip temperature does not exceed 150 ° C \ -3.3V regulator can provide peak~150 mA, provided that the regulator's chip temperature does not exceed 150 ° C \ -5V logic, with 3.3V compatible input \ -20 digital input/output pins: 6 of which can also be used as PWM output, and 6 can also be used as analog input \ -6-pin ICS P socket, used for reprogramming \ -32 KB flash memory, 0.5 K for boot loading program, providing 31.5 KB \ -16 MHz clock speed aft
