Universal EXTension (UEXT) is a circuit of a connector that includes a power line and three serial data interfaces: UART, I2C, SPI. Developed by Olimex and is open and free. UEXT specification.

UEXT connector consists of 10 pins, 5 pins in two rows in a plastic frame. The distance between pins is 2.54 mm. The connector connects to a 2x5 (10-pin) IDC socket and usually connects to flat cable. See also [1].

UEXT-connectors on the Wiren Board controller board

There are two UEXT-connectors on the board of Wiren Board controller v2.8. But in the second connector, the MISO, MOSI, SCK lines are duplicated with the corresponding pins of the first connector. TxD and RXD lines are duplicated with RS-485 inputs.

2 GND S S Ground
3 TxD O PP Debug UART/en Tx
4 RXD I PP [Debug UART/en]] Rx
5 SCL O OD Hardware I2C, SCL
6 SDA I/O OD Hardware I2C, SDA

1 3.3 V S S +3.3 volt
2 GND S S Ground
3 TXD O PP sc16is752 UART0 Tx parallel to RS-485

7 MISO I PP SPI Bus, MISO
8 MOSI O PP SPI Bus, MOSI
9 SCK O PP SPI Bus, SCK
10 SSEL O PP GPIO 91 SPI Bus, CS


Ports 3,4 (UART) of the UEXT2 connector are connected to the chip SC16IS752/en and are present only in modifications with this chip (GPS or RS-485 options). These ports are connected in parallel to the transceiver RS-485/en and cannot be used simultaneously with RS-485/en.
