The first Arduino board based on an ARM processor. Features 2 channel 12-bit DAC, 84 MHz clock frequency, 32-bit architecture, 512 KB flash and 96 KB SRAM. Unlike most Arduino boards, it operates on 3.3 V and is not 5 V tolerant. Arduino Yún [21] ATmega32U4, [22] Atheros AR9331 16 MHz, 400 MHz Arduino 68.6 mm × 53.3 mm [ 2.7 in × 2.1 in ]
PMA-1 is used to connect the Zarya control module with Unity node 1, Space Shuttles used PMA-2 and PMA-3 for docking. International Docking Adapter (IDA): [35] Converts APAS-95 to the International Docking System Standard. IDA-1 was planned to be launched on SpaceX CRS-7 until its launch failure, and attached to Node-2's forward PMA.
IDA-2 was delivered successfully on SpaceX's CRS-9 mission in July 2016, and then installed on PMA-2 in August of that year during a spacewalk by Jeffrey Williams and Kathleen Rubins as part of Expedition 48. [14] Crew Dragon Demo-1 was the first spacecraft to dock at this port on 2 March 2019.
The first-generation IOIO boards (known as IOIO V1) contain the following on-board features: [34] [35] This generation only supports USB slave mode, and requires a USB master as the host (PC or newer Android phones). [2] [7] The IOIO V1 is a 3.3 V logic level device, and features a 5 V DC/DC switching regulator and a 3.3V linear regulator. [36]

The base board is similar to the STK500, in that it provides a power supply, clock, in-system programming, an RS-232 port and a CAN (Controller Area Network, an automotive standard) port via DE9 connectors, and stake pins for all of the GPIO signals from the target device.
2.1 The first non addressed SNPD node is selected. It is identified by having the input D 1 low (D 2 of previous node). 2.2 The selected node takes the address from the LIN configuration message 2.3 The detected node turns on the pull-down at the output D 2 2.4 Steps 2.1-2.4 are repeated until all slave nodes are assigned an address
Serial port (COM port) - At one time the most popular method. Serial ports usually lack adequate circuit programming supply voltage. Most computers and laptops newer than 2010 lack support for this port. Socket (in or out of circuit) - the CPU must be either removed from circuit board, or a clamp must be attached to the chip-making access an issue.
