VisionCB-8M-ADV v.1.1 Datasheet and Pinout

General description

VisionCB-8M-ADV is a carrier board for the VisionSOM-8Mmini family of computer-on-modules which are powered by NXP SOC iMX8Mmini (quad core ARM Cortex-A53+ single Cortex-M4). 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, Ethernet, 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. VisionCB-8M-ADV carrier board is equipped with HDMI/LVDS and MIPI-DSI video outputs, 24-bit audio codec, PCIe (M.2 key M) socket (2242, 2260, 2280), on-board RTC with battery socket, RS-485 and CAN FD interfaces. VisionCB-8M-ADV carrier board is equipped with Segger J-Link debugger and Linux serial console port on USB vCOM.

Electrical parameters

M.2 socket - key M (PCIe interface, J100)

Note:
1. IO[14..11] are used optionally.
2. PCIe is single lane interface.
3. M.2 socket is key M type.
4. By default CONFIG[3..0]=1111b.

Camera MIPI-CSI interface (J301, FPC/FFC 0.5mm)

Note:
1. 1st pin of J301 connector is at the top of the image.
2. The I2C1 interface is common to MIPI-CSI interface and audio codec.

Display MIPI-DSI interface (J900, FPC/FFC 0.5mm)

Note:
1. 1st pin of J900 connector is at the top of the image.
2. For configuration purposes is used I2C2 interface.
3. MIPI-DSI interface is muxed with J901 (DISP MUX) between J900 (raw MIPI-DSI output) and HDMI/LVDS converter.
4. The I2C2 interface is common to onboard RTC, HDMI-DDC, LT8912B bridge configuration and MIPI-DSI display controller.

HDMI and LVDS display interface

The VisionCB-8M-ADV board is equipped with MIPI-DSI > HDMI/LVDS hardware bridge (converter) based on Lontium LT8912B.
HDMI signals are available on standard HDMI connector (marked as HDMI), LVDS signals are connected to 20 pin 2.54mm 2 row connector (marked as LVDS).
The VisionCB-8M-ADV board is equipped with jumper (DISP MUX) for selecting displays: MIPI-DSI or HDMI/LVDS.

Note:
1. The I2C2 interface is common to onboard RTC, HDMI-DDC, LT8912B bridge configuration and MIPI-DSI display controller.
2. MIPI-DSI interface is muxed with J901 (DISP MUX) between J900 (raw MIPI-DSI output) and HDMI/LVDS converter.

Note:
1. 1st pin of J902 connector (LVDS) is marked with arrow.
2. The I2C2 interface is common to onboard RTC, HDMI-DDC, LT8912B bridge configuration and MIPI-DSI display controller.

USB Console Port and Segger J-Link debugger

Notes:
1. Linux console port (UART4 in MPU) uses vCOM interface provided by built-in debugger Segger J-Link.
2. vCOM can be disconnected from MPU with JP801 (jumper CON in position ON or OFF).
3. Lines TXD and RXD of UART4 are easy to monitoring thanks to using J304 gold-pins.
4. Debug JTAG interface can be disconnected from MPU with JP801 (jumper J-LINK in position ON or OFF).
5. J-Link activity is monitored with ACT LED.

MicroSD card interface (J308)

24-bit stereo audio codec

The VisionCB-8M-ADV board is equipped with 24-bit stereo codec - Nuvoton NAU88C22YG - with integrated audio amplifier.
The NAU88C22 is a low power, high quality CODEC for portable and general purpose audio applications. In addition to precision 24-bit stereo ADCs and DACs, NAU88C22YG integrates a broad range of additional functions to simplify implementation of complete audio system solutions. The NAU88C22 includes drivers for speaker, headphone, and differential or stereo line outputs, and integrates preamps for stereo differential microphones,significantly reducing external component requirements.

Note:
1. The I2C1 interface is common to MIPI-CSI interface and audio codec.

On-board RTC

The VisionCB-8M-ADV is equipped with on-board RTC module based on NXP PCF85263AT.
The PCF85263A is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power consumption and with automatic switching to battery on main power loss.
The RTC can also be configured as a stop-watch (elapsed time counter). Three time log registers triggered from battery switch-over as well as input driven events.
Featuring clock output and two independent interrupt signals, two alarms, I2C interface and quartz crystal calibration.
RTC can be powered by an external CR1220 battery (socket J302).
