OKdo E1 Development Board

OKdo E1 Development Board


OKdo, part of the Electrocomponents Group, introduced its first own-branded single board computer (SBC), the E1.

The OKdo E1 is an ultra-low-cost Development Board based on the NXP LPC55S69JBD100 dual-core Arm Cortex® M33 microcontroller. The E1 board is perfect for Industrial IoT, building control and automation, consumer electronics, general embedded and secure applications.
