Most boards have 3.3V/5V power, ground (GND), three to 11 analog plus ten digital I/O, power, transmit (TX), and receive (RX) pins which mirror the onboard LEDs.

The pin designations are located within pyb.Pin.board . For an Arduino based board, the board pin designation would be D0 to D13. A developer could easily modify the board numbers, however, by ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

The Metro board is also equipped with 19 GPIO pins, 6 of which are Analog and 2 of which are reserved for the USB-serial converter. There’s also 6 PWMs available on 3 timers offering 1 x 16-bit ...

Features of the new Arduino Due development board include, a SAM3X8E processor from Atmel, based on the 32 bit ARM Cortex M3 architecture running at 84MHz, USB 2.0 interface that can be used as a ...

This, of course, led him down the path towards the Sanguino, the ATMega644-based dev board with many more IO pins than Arduino boards based on the ATMega328.

This board also features 128 MB of RAM, 8MB of Flash and the usual compliment of Arduino pins in a Leonardo-compatible layout. Also on the SoC is a PCIE bus, Ethernet, a USB 2.0 host, and an SD card.

The new board is called Giga R1 WiFi, and has an Arm Cortex-M7 running at 480MHz and M4 at 240MHz, with two additional connectors for the additional IO, one of which can handle a camera.
