Shenzhen-based ArmSoM has introduced a low-cost computer-on-module, constructed round Rockchip’s RK3506J system-on-chip — and out there direct from the corporate for simply $15 in single-unit portions: the ArmSoM-CM1.
“ArmSoM-CM1 is a computer-on-module (COM) based mostly on the Rockchip RK3506J (tri-core [Arm] Cortex-A7 + single-core Cortex-M0),” the corporate explains of tis compact board. “It contains a wealthy set of peripheral interfaces reminiscent of SAI, USB 2.0 OTG [On-The-Go], RMII, and CAN.
