Raspberry Pi style SBC serves up i.MX8M Mini for $90

Sep 2, 2021 — by Eric Brown 7,976 views

Geniatech has launched a $90 “XPI-iMX8MM” SBC that runs Linux on an i.MX8M Mini with up 1GB to 4GB RAM, 8GB to 128GB eMMC, and 40-pin GPIO.

Geniatech has begun selling a Raspberry Pi sized SBC with NXP’s 1.8GHz, quad -A53 i.MX8M Mini. The XPI-iMX8MM follows Geniatech’s larger APC810 SBC, which is equipped with the i.MX8M. The SBC has the same Raspberry Pi size and layout as its Amlogic S905X powered XPI-S905X.

The closest match to the XPI-iMX8MM is Avnet/Embest’s Raspberry Pi style MaaxBoard Mini, which sells for $72.50 with 2GB RAM and an empty eMMC slot but is currently out of stock. Geniatech sells the XPI-iMX8MM with 1GB (expandable to 4GB) RAM and 8GB (expandable to 128GB) eMMC for $90.

The features are almost identical to the MaaxBoard Mini except that Geniatech has adds an HDMI port. It still runs up against the i.MX8M Mini’s 1080p limit, however. The XPI-iMX8MM also adds a composite A/V port, offers a wider standard operating range, and adds a -40 to 105°C tolerant model. The MaaxBoard Mini, meanwhile, adds two user buttons, a PMIC, and a heatsink, and the WiFi/BT module appears to be standard rather than optional.

Larger, more feature rich i.MX8M Mini options include SolidRun’s $170 and up HummingBoard Ripple, which is limited to 2x USB 2.0 ports, but provides M.2, mini-PCIe, and SIM slots plus a MikroBus interface. There are many more Mini-based SBCs from Estone, Gateworks, Garz & Fricke, and others, but most are not publicly priced.
