Compulab presents low-cost NXP i.MX93 embedded platform

May 31, 2023 — by Giorgio Mendoza 1,114 views

Compulab introduced today a low-cost embedded device built around a dual-core ARM Cortex-A55 and the Arm Ethos U-65 microNPU. The company has also launched a compatible carrier board with mainline Linux support and RTOS.

The Compulab UCM-iMX93 is built around the same NXP processor as the VAR-SOM-MX93 (Variscite) launched earlier this year. There are three SoM variants available: the C1700D (Dual-Core), the C1500D (industrial temp. grade) and the C1700S (Single-Core).


  • NXP i.MX 93 — Dual-core Cortex-A55 (up to 1.7GHz); Single-core Cortex-M33 (up to 250MHz), Ethos-U65 microNPU

All SoM variants include the real-time Arm Cortex-M33 co-processor. The SoM can be ordered with 512MB/1GB/2GB DRAM and 8GB/16GB/32GB/64GB eMMC.

Ethernet, Wi-Fi and Bluetooth 5.3 support is optional. The datasheet indicates that the SoM provides support for up to 79x GPIOs, 7x SPI, 6x I2C, 7x UART, 2x I2C/SAI, 4x ADC channels and 6x PWM.

Compulab has also launched an evaluation kit (UCM-iMX93) which includes a SB-UCMIMX93 carrier board, a 5″ WXGA LCD w/ capacitive touch panel, Wi-Fi antennas, USB cables and a 12V power supply as shown above. Refer to the Compulab Wiki for more information.

Furthermore, the company states that they will provide “technical support for 12 months and the Eval Kit will be accepted for refund if the user finds the product not suitable for his needs (45-day trial period).”
