TQ unveils i.MX 8M Plus LGA module and evaluation single board computer

We’ve seen plenty of systems-on-module based on NXP i.MX 8M Plus AI processor announced at Embedded World 2021 either with edge or board-to-board connectors.

TQ TQMa8MPxL is a bit different as an i.MX 8M Plus LGA (Land Grid Array) system-on-module meant to be soldered on a carrier board. The company also took the occasion to unveil STKa8MPxL evaluation kit based on TQMa8MxML in single board computer format to demonstrate its new LGA module.

Pricing, availability, advantages of LGA modules

Both the TQMa8MPxL system-on-module and the STKa8MPxL Starterkit/single board computer appear to be available now, but the company did not publish any pricing information. More details may be found on the announcement and product page.

As noted in the introduction, most modules are using edge or board-to-board connectors for easy upgrade and replacement, but some other relies on castellated holes, and need to be soldered. LGA modules are harder to find, and previously we covered TechNexion XORE LGA System-on-Module based on NXP i.MX 8M Mini with the key advantage of such being being the tiny form factor and low height allowing integration into compact/thin designs. I also assume soldered-on modules should manage vibrations and shocks better than modules inserted into a socket.
