96Boards launched B-96AI & TB-96AIoT – their First Systems-on-Module (SOM)

96Boards launched B-96AI & TB-96AIoT – their First Systems-on-Module (SOM)

Linaro announces 96Boards System-on-Module (SOM) Specification and Rockchip powered compute SOM design.

At the first day of Linaro Connect Bangkok 2019, 96Boards SoM specifications have been announced, together with the introduction of Rockchip RK3399Pro powered TB-96AI and Rockchip RK1808 based TB-96AIoT, which are the first 96Boards compliant SoMs, along with 96Boards SoM Carrier Board.

96Boards System-on-Module Specifications

Two form factors are defined as SOM-CA and SOM-CB with a maximum of four 100 pin Connectors. The X1 connector is mandatory on all SOMs. The defined interfaces are shown in the table below.

List of signals associated to each connectors:

  • X1 – SoM managements, 1x UART, 2x I2C, 1x SD, 2x SPI, 1x CAN, 1x multiplexed DSI/eDP/LVDS, 2x USB 2.0 OTG/Host, 1x USB 2.0/3.0 host
  • X2 – 1x I2S, 1x multiplexed I2S/PCIe, 6x multiplexed GPIO/analog audio, 1x multiplexed MIPI CSI/DSI/Audio, 1x Ethernet, 1x PCIe 4x, 1x USB 2.0 OTG/Host, 1x USB 2.0/3.0 device, 1x smartcard/muxed with PCIe, 1x SATA
  • X3 – 7x GPIO, 4x MIPI CSI inc. 1x multiplexed with MIPI DSI, 1x MIPI DSI multiplexed with MIPI CSI,  1x Ethernet, 1x HDMI
  • X4 – 2x UART, 2x I2C, 1x I2S mux with SATA, 7x GPIO mux with ADC/SPI, 1x SD. 2x SPI, 2x CAN (1x mux), 1x PCIe x4, 1x USB 2.0 OTG/Host, 1x USB 2.0/3.0 host, 1x SATA mux with I2S

That’s plenty of multiplexed signals which at first sight open the door for potential incompatibilities between modules.

The 96boards Wireless specification defines wireless modules with 802.15.4, BLE, WiFi, LoRa, NB-IoT, LTE-M, and future wireless standards. Again two form factors are specified with SOM-WA and SOM-WB and 20-pin are defined with GPIO, PWM, UART, SD, SPI, I2C, ADC, USB, SWD, and VDD/ground.



The TB-96AI , equipped with RK3399Pro, has an integrated neural network processor NPU, computing power of up to 3.0 Tops, and offers compatibility across a variety of AI architectures. It can be combined with the backplane to form a complete industry application motherboard, and be applied to various embedded artificial intelligence fields.


Equipped with the RK1808 AIoT chip, 22nm process, ultra low power consumption with Independent NPU and AI computing power of up to 3.0Tops, the TB-96AIoT also provides rich interfaces and strong scalability.

96Boards SOM Carrier Board

The 96Boards SOM Carrier Board is compatible with both the TB-96AI and TB-96AIoT. It is designed to suit different markets and demonstrates how easy it is to support multiple different SOMs.

Key features:

  • 4x 100-pin connectors for 96Boards SoM
  • Storage – Micro SD card
  • Video Output – 4-lane MIPI DSI (eDP), HDMI 2.0, LCD header
  • Audio – 3.5mm audio jack, speaker header
  • Camera – 2x 4-lane MIPI CSI connectors
  • Connectivity – 2x Gigabit Ethernet, Dual band WiFi + Bluetooth module
  • USB – 3x USB 3.0 ports, 1x USB type-C port
  • Expansion
    • 2x PCIe sockets
    • LS & HS connectors for mezzanine products
    • CAN bus header
  • Debugging – micro USB debug port, JTAG
  • Misc – Reset, power, and 2x user buttons; user LEDs, and system LEDs; RTC battery socket
  • Power Supply – 12V DC
