On the other hand, the FPGA incorporated is the Efinix T120F324 which comes in a compact 324-ball FineLine BGA package. With support for various interfaces like MIPI-CSI connectors for both receiving and transmitting data, LVDS transmitter and receiver connectors with 20 lanes each, and JTAG headers for configuration, it provides versatility for different applications. 

Additionally, it offers user-selectable voltages, access to a 40-pin GPIO header, and multiple oscillators for precise clock inputs, making it a robust and adaptable component of the board’s architecture.

Regarding peripheral connectivity, the Vaaman offers a comprehensive range of interfaces, including PCI, HDMI, USB, MIPI, audio, Ethernet, Wi-Fi, Bluetooth, BLE, LVDS, and GPIOs as shown below.

The company states that they are developing a customized platform called Gati to enable end-to-end solutions related to convolutional neural networks which can be deployed on the Vaaman board.

Vaaman is designed to potentially address various applications, including object classification and detection, human presence and gesture detection, edge machine vision, cryptographic algorithms, and video and image decoders, as advertised.
