Arducam launches $30 ToF depth camera for Raspberry Pi devices

Sep 1, 2022 — by Giorgio Mendoza 758 views

Following the launch of the Hawkeye 64MP camera back in April, Arducam has recently launched a low-cost Time of Flight (ToF) camera specifically designed for the Raspberry Pi embedded platform. The operating depth range for this camera spans from 2m (±4cm) to 4m (±2cm) and it can be used in outdoor environments as well.

According to the specifications, the camera module has a resolution up to 120fps. The performance drops depending on the Raspberry Pi device used. For example, the Raspberry Pi 4 and the CM4 can get up to 30fps. The frame rate is halved to 15fps on the Pi Zero 2 W while the Pi 3B can achieve up to 10fps. The Pi Zero is also supported but the resolution drops to 5fps.

The FAQ section mentions that this ToF doesn’t need an external light source since it features an onboard laser, in this case a 940nm VCSEL illuminator. The resolution is set to always work at full resolution (240 × 180) but additional options might be added in the future.

For software development, the company provides support for Raspberry Pi OSes (Bullseye 32-bit/64-bit or later) as well as SDKs in C, C++ and Python. Arducam might also provide support for NVIDIA Jetson devices and ROS depending on the campaign goals reached.
