Tiny, temp-resistant SBC runs Android 6.0 on Snapdragon 820

Apr 3, 2017 — by Eric Brown 3,228 views

iWave has launched a rugged, 56 x 50mm “iW-RainboW-G25S” SBC with a Snapdragon 820 SoC, up to 6GB of LPDDR4 RAM, up to 128GB eMMC, HDMI, WiFi, BT, and GPS.

The iW-RainboW-G25S single board computer, which iWave also calls the APQ8096 SBC and Snapdragon 820 SBC, runs Android Marshamallow on Qualcomm’s quad-core APQ8096 SoC, better known as the Snapdragon 820. Designed for high-end embedded applications that require high processing power, graphics and multimedia capabilities, the SBC weighs in at a tiny 56 x 50mm and supports -20 to 85°C temperatures.

The iW-RainboW-G25S is only the second Snapdragon 820 based SBC we’ve seen after Inforce Computing’s recent Inforce 6640, although a number of 820-based COMs have shipped. The Inforce 6640 has a much larger 100 x 70mm Pico-ITX footprint and a more extensive set of features, but is limited to commercial temperature support. iWave’s more minimalist board omits the GbE port, and depends solely the 802.11ac dual-band radio, which comes on a module that also provides Bluetooth 4.1. A Qualcomm IZat GPS module is also available.

Qualcomm’s Snapdragon 820 SoC integrates four 14nm FinFET fabricated “Kyro” cores that roughly mimic the ARMv8 Cortex-A72 design. The Kryo cores — two at 2.15GHz, and two at 1.6GHz — offer up to twice the performance and twice the power efficiency of the Cortex-A57 cores on the Snapdragon 810. There’s also a 624MHz Adreno 530 GPU with up to 40 percent improvement in graphics over the previous Adreno 430. An upgraded Hexagon 680 DSP and a 14-bit Spectra image signal processor (ISP) are also onboard.

The iW-RainboW-G25S ships with 3GB of LPDDR4, expandable to 6GB, which is the highest RAM maximum we recall seeing on an ARM-based SBC. You also get 32GB eMMC by default, expandable to 128GB. A microSD slot is also available.


Real-world coastline ports are limited to a micro-HDMI port, a micro-USB port used for power, and an audio jack. A USB 3.0 port with Type-C connector is said to be optional.

MIPI-DSI and -CSI connectors are available along with some I2C and GPIO on a 30-pin connector. Other features include some tactile switches, a PMIC, and a battery connector.
