Seeed has placed $100 preorders with Google Coral Dev Board Mini running Linux on a quad-core A35 MediaTek 8167s processor with 4-TOPS Edge TPU. Mini offers 2GB LPDDR3, 8GB eMMC, WiFi/BT, HDMI microphone, MIPI-DSI/CSI, 2x Type-C and 40-pin GPIO.
In January, Google announced the release of a miniature version of Coral Dev Board and the introduction of a Coral Accelerator Module with Google’s Edge TPU 4-TOPS. Seeed has now opened pre-orders for $100 of Minis with the Coral Accelerator module, with deliveries starting at the end of the month.

The specifications have remained largely the same as in the original announcement, but with some additional details. Unlike the Coral Dev Board style sandwich, which fell to a minimum of $130 at Amazon, the Coral Dev Board Mini does not use the NXP i.MX8M and the Edge-TPU equipped with Coral SOM, but immediately includes the less powerful MediaTek 8167s SoC and the new Edge-TPU solder module. Like Coral Dev Board, the mini version runs on Mendel, a version of Debian Linux from Google.
The low power consumption MediaTek 8167s model is equipped with 4 Cortex-A35 cores and a PowerVR GE8300-GPU from Imagination. The hourly frequency is not fixed, but it is known that the SoC can reach up to 1.3 GHz. Compared to the higher resolution MediaTek 8167a and 8167b siblings, SoC offers extensive audio interfaces, including I2S and 8-channel TDM input and output.
In the first announcement, Google stated that SoC exceeds 720P video encoding and decoding. The MediaTek 8167s supports 1280 x 800 pixel displays and H.264, H.265 and HEVC decoding and offers 12 megapixel ISP camera and H.264 encoding.

Coral Dev Board Mini, also known as Dev Board Mini, is used to evaluate the new acceleration module. Edge TPU is a shortened version of Google’s TPU. It is designed to run the TensorFlow Lite ML and AutoML Vision Edge models for high speed ML conferencing on low power Linux systems. Google describes AutoML as a library of fast and highly accurate custom image classification templates. According to Google, the Edge TPU works with 4 TOPS and consumes 0.5 watts per TOPS (2 TOPS per watt).
The mini Coral Dev Board measures 64 x 48 mm and is therefore smaller than the 88.1 x 59.9 mm of the original board. The SBC comes with 2 GB LPDDR3 and 8 GB eMMC. Features removed from the original set of devices include a microSD slot and GbE and USB 3.0 host ports. Two USB 2.0 type C ports remained, and the HDMI 2.0a port was reduced to Micro HDMI 1.4.
Like a large board, the Mini is equipped with 802.11ac technology with Bluetooth (now 5.0) and offers 4-band MIPI DSI and CSI2 FFC connectors. It is also equipped with a 40-pin GPIO connector and a 3.5 mm audio connection. You will receive a digital PDM microphone and a 2-pin stereo speaker jack, not a 4-pin jack. We saw no indication of a radiator on the prototype picture.
As mentioned in Hot Hardware, Dev Board Mini competes with the Nvidia Jetson Nano Developer Kit for $99 and the new Nano 2GB Developer Kit for $59. The Jetson nano modules that control the kits provide artificial intelligence processing using 128-core Maxwell GPUs. Unlike the Nano-Kits, it is supposed to be an open source array, just like the original Coral-Dev-Kit, although the open source files don’t seem to have been placed yet.
