OKdo, one of the RS Component family of companies, has introduced its first own-branded single board computer – aimed at those developing secure IoT endpoints.

Called ‘E1’, it was developed with NXP and is built around an Arm Cortex-M33-based microcontroller, NXP’s LPC55S69.

“In addition to forming the basis for secure IoT endpoints, the E1 is a great platform for evaluating the LPC55S69,” according to OKdo.

On-board the MCU are: a cryptographic co-processor, a DSP hardware accelerator, a security module for the real-time encryption and decryption of data and code in the chip’s flash and support for secure boot – amongst these are: TrustZone-M, AES-256 encryption, AES-256 decryption engine, a physical unclonable function (PUF) and a true random number generator (TRNG).

OKdo-E1Development support comes from NXP’s MCUXpresso integrated development environment (IDE).

“A passive companion PCB allows developers to add other functions from Arduino-compatible shields,” according to the company

– which I cannot find on the website – though it looks like the board has space for Mikroe headers.
