Pi-like SBC offers Rockchip RK3128 for $25
Sep 21, 2020 — by Eric Brown 3,630 viewsGeniatech has launched a $25 “XPI-3128” SBC that runs Linux or Android on a quad -A7 Rockchip RK3128 with 512MB RAM, 8GB eMMC, optional 802.11ac/BT 4.2, and Pi-like ports, layout, and 40-pin GPIO.
Last year, Geniatech introduced a series of Developer Board (DB) SBCs based on Rockchip SoCs led by the RK3399Pro-based DB3399 Pro. Now the company has launched an XPI-3128 SBC built around the lowlier, quad-core, Cortex-A7 Rockchip RK3128, which is also found on Firefly’s Firefly-RK3128 and Commell’s Pico-ITX form-factor LP-150 SBCs.

The Raspberry Pi-like XPI-3128 supports Linux or Android 7.1 on the 1.2GHz RK3128, which integrates a Mali-400MP2 GPU. You also get 512MB to 2GB RAM, 8GB to 64GB eMMC, and a microSD slot. As noted by the CNXSoft post that alerted us to the SBC, Geniatech has added a shopping page for individual sales where the XPI-3128 is listed for $25 in a minimal, 512MB/8GB configuration.
The $25 price does not appear to include the featured Marvell Avastar 88W8897 wireless module with dual-band 802.11ac and BT 4.2. The 88W8897, which is deployed on a daughtercard module, is now sold by NXP after the chipmaker acquired Marvell’s WiFi/BT portfolio earlier this year. The 88W8897 is listed on one of Geniatech’s two specs sheets while the other lists only a generic “WiFi jack,” which is said to support multiple WiFi modules.

The 85 x 56mm XPI-3128 is a close match with the Raspberry Pi 2, with features like 4x USB 2.0 host, 10/100 LAN, HDMI 1.4, and 40-pin GPIO. However, it lacks the Pi’s Composite audio/video and MIPI-DSI/CSI interfaces.

Further information
The Geniatech XPI-3128, which is also listed as the XPI_3128, is available starting at $25 with volume discounts available. More information may be found on Geniatech’s product page and shopping page.
A bit too little too late. Price is not bad per se, but there’s lot of competition.
Their XPI-S905X seems a much more interesting solution; roughly the same hardware of the glorious Odroid C2, with only 100Mb Ethernet but 8GB eMMc flash included, at only $35.
