NXP nomenclature for their i.MX 8M processors can be a little confusing. First discovered in 2016, the original i.MX 8M processor family comes with one to four Arm Cortex-A53 cores, a real-time Cortex M4 core, targets multimedia application with FullHD or 4K decoding/encoding support and is manufactured using a 28nm process.
NXP then announced i.MX 8M Mini processor family in February 2018 with a 14-nm FinFET processor allowing a higher maximum CPU frequency of 2.0 GHz, less video output interfaces (no HDMI, nor DisplayPort), and optional Full HD video encoder and decoder, .e.g no 4K. Finally, earlier this year, the company unveiled NXP i.MX 8M Nano further power-optimized with the same 14nm manufacturing process, but a lower frequency of 1.5 GHz, and a Cortex-M7 core replacing the Cortex-M4 core found in previous i.MX 8M processors. This allows i.MX 8M Nano SoC to have a 2W TDP, and achieve sub-watt power consumption in IoT edge projects.
We’ve already written about i.MX 8M Mini based hardware, but so far no i.MX 8M Nano system-on-module or single board computer had come to our attention, and iWave Systems iW-RainboW-G34M-SM system-on-module will come with either Mini or Nano version of the processor.

The company will provide Linux 4.0, and Android Oreo BSP’s for the modules. Typical applications for iWave Systems’ latest modules include digital signage, industrial HMI, home automation, audio/video streaming devices, and general embedded applications
iW-RainboW-G34M-SM system-on-module based on i.MX 8M Mini will soon be sampling and shipping to customers, while the i.MX 8M Nano system-on-module is expected later this year. iWave Systems will also offer a development platform with a TFT panel to evaluate all the features of the i.MX8M Mini/Nano CPU.
