TL;DR · WeSearch summary

Mecha Comet's April update details progress on the I.MX95 mainboard, which is nearing release to manufacturing, while ongoing issues with WiFi performance persist. Thermal design has improved significantly with an extended aluminum frame for better heat distribution, and reliability testing of the GPIO connector is underway. The device has passed EMI emissions testing, and waterproofing has been enhanced with an IPX7-rated connector replacing the headphone jack.

Key facts

▪The I.MX95 mainboard is seven days away from release to manufacturing, with final review comments from NXP being incorporated.
▪WiFi performance issues are still unresolved, but the team is working with U-Blox and NXP to identify problems related to access point behavior and power-saving modes.
▪Thermal design improvements have been achieved by extending the aluminum middle frame under the battery for more even heat distribution.
▪The front 40-pin GPIO connector is undergoing rigorous durability testing using a motorized pogo pin jig to simulate repeated connections.
▪EMI emissions for the I.MX8M Plus DVT are now within limits, and pre-certification testing is planned for May; all connectors are now waterproof, including the new IPX7-rated port.

Hey everyone, I am back with April’s set of updates - albeit a bit delayed. We have a lot going on in parallel, but lets catch you all up.HardwareI.MX95 Design close to completionWe’ve spent almost all of April getting the I.MX95 version of the mainboard to the finish line. We are now 7 days away from releasing to manufacturing. A couple of days, we have received review comments from NXP as well and are working to incorporate them. We have had some surprises lately, but things overall look good-to-go.Still troubleshooting the WiFi Issue 😢This one is a bummer. I spoke about the WiFi issue in the last update; we unfortunately don’t have it resolved yet entirely. But we are getting closer to identifying the performance issue with the module.
