SpaceCB-8Mplus-ADV v.1.1 Datasheet and Pinout

General description

SpaceCB-8Mplus-ADV is a carrier board for the SpaceSOM-8Mplus family of computer-on-modules which are powered by NXP SOC iMX8Mplus (quad core ARM Cortex-A53+ single Cortex-M7 + Neural Processing Unit). A carrier board, together with a System on Module (SoM), makes a complete development platform similar to SBC. The carrier board houses the most common interfaces such as USB 3.0, USB-C, dual gigabit Ethernet, HDMI, PCIe, etc. A large variety of interfaces allows to use it as both a complete development platform or as a stand-alone end-product.
The carrier board connects with the SoM via a standard SODIMM connector.
SpaceCB-8Mplus-ADV carrier board is equipped with HDMI + LVDS + MIPI-DSI video outputs, 24-bit audio codec, PCIe 3.0 (M.2 key M) socket (2242, 2260, 2280), RS-485 and CAN-FD interfaces.
SpaceCB-8Mplus-ADV carrier board is equipped with Segger J-Link debugger and Linux serial console port on USB vCOM.

RS-485 semiduplex serial interface


The SpaceCB-8Mplus-ADV board is equipped with low-voltage RS-485 physical layer interface MAX3485.
The RS-485 is connected to default UART2 (TxD, RxD) channel and pins. Transmission control line DE is controlled by MPU GPIO.

Signal Default MPU pin name Description
RO UART2_RXD Data received by MPU
DI UART2_TXD Data transmitted by MPU
DE GPIO5.05 Transmitter Enable (active high) signal

Note:
1. nRE line of MAX3485 is permanently connected to GND.
