Customizable carrier for OMAP4430 COM has RPi style CSI-2 port

Jul 7, 2016 — by Eric Brown — 519 views

Gumstix released a customizable carrier board for its tiny OMAP4430-based DuoVero COMs, featuring touchscreen and Raspberry Pi style CSI-2 camera support.

Gumstix has launched an open-source “Garret 50C” carrier board for its 58 x 17mm, dual-core DuoVero computer-on-module family, the company’s higher-end alternative to its single-core Overo COMs. The board was developed with the company’s online Geppetto DIY design and quick-turn prototype manufacturing service, which customers can use to customize the board.

The DuoVero is built on a Texas Instruments OMAP4430 SoC with dual 1GHz Cortex-A9 cores and a 3D-accelerating PowerVR SGX450 GPU. The 58 x 17mm module has dual 70-pin expansion connectors, and is supported with open-source Linux development kits, including Yocto Project build system support.

The COM is equipped with 1GB RAM, and boots from an on-board microSD card slot. Earlier carrier boards for the DuoVero included the Chateau and the Parlor.

The $139 Garret 50C carrier board appears to support the entire DuoVero family, including the original $169 Crystal model and the newer, WiFi and Bluetooth enabled Zephyr COMs, which are available in $179 and $199 models. The combined carrier/COM product is designed for IoT applications, such as home automation control interfaces or handheld device development, says Gumstix.

The 120 x 85mm Garret 50C features a parallel RGB touchscreen interface that connects to a 5-inch NewHaven capacitive display. Other features include a Fast Ethernet port, dual USB type-A ports, a pair of micro-USB ports for console and device functions, and an FTDI FT232RQ USB-to-UART interface for connecting serial devices. There’s also a “Raspberry Pi” CSI-2 style camera connector, plus 3.5mm audio line in/out jacks.

You can power the board with a 5.0V wall adapter or a LiPo 2-cell balance connector. The carrier board also provides a real-time clock function and backup battery holder. Customizations available with Geppetto include adding WiFi or LTE, removing selected ports, and swapping out the 5-inch LCD connector for a 7-inch connector. Presumably other modifications can be implemented through Geppetto, as required for unique applications.

Further information

The standard Garret 50C carrier board design is available now for $139, without the DuoVero COM. More information may be found at the Gumstix Garret 50C product page. More about Geppetto is here.
