Since the last update we have created testing banks to test for mechanical issues in multiple devices simultaneously. Designed and printed by @maximephan, they're awesome and have saved us a lot of time! While the rate of mechanical issues has been relatively low (around 4%), the significant number of messages we have received about MicroSD cards failing over time has convinced us to replace all of them with better ones. We discovered that this issue is caused by the cutting off of power to the MicroSD card when the FunKey S is turned off using the Instant Action feature. As the microcontrollers inside our chosen MicroSD cards are still performing operations when power is shut off to them, they tend to break over time. With each manufacturer having their own microcontroller with little to no documentation available online, we have been unable to solve this issue with the current MicroSD cards and have therefore decided to source replacement cards that do not malfunction when their power source is shut off. To simultaneously test the many MicroSD card candidates that we received, we created another set of testing banks that use electro-magnets to turn FunKey S systems on and off while constantly writing data to them. The most promising of these cards not only does not malfunction under the testing conditions, but also meets the U3 standard with a write speed of 30 MB/s. After the significant shipment delays, upgrading the MicroSD cards at no cost to backers is the very least that we can do. We'll continue to keep everyone informed about the state of the MicroSD cards, but for now this card appears to be a great candidate! |
