I am interested in purchasing the Raspberry Pi Pico 2 (SparkFun SKU: DEV-26124). I am wondering which silicon revision this dev board is built with. Can someone confirm if it is the A2 variant or the A4 variant? The product pictures show A2 on the IC marking, but the A4 is the newer production version of the chip that fixes various silicon issues. I am interested in buying the dev board with the A4 revision of the chip specifically.
We can check physical stock on Thursday to determine, hang tight for now 
No reply but it is highly likely it is A4 which was released over a year ago.
