This week at my desk, we worked on a couple different I2S DACs – we’ve stocked the UDA1334A, but that’s technically discontinued – it was great because it doesn’t require an MCLK that some boards like the raspberry pi don’t have, and doesn’t need I2C configuration either. The PCM51xx series is similar, and we finally designed a board with it, and prototypes were tested.

Next, we started attacking the TLV320DAC3100 from last week, which is a beast – we were nervous that the Claude interface would message limit us too much for all the setters/getters. So, we are trying an AI API desktop interface. We pay per token, but it’s still an excellent deal.

Finally, we got the first draft of a new Pi Compute Module backpack design to review: we used to stock a PiCam Module – recently, we went to restock it, but the vendor hasn’t replied to our emails for many months. This inspired us to design something better, so we tasked Timon with designing something for us…let’s see what he came up with!

The Great Search – Tall Contacts for Compute Module

Timon is designing a backpack for the Pi Compute Module, and we’re stuffing it full of fun features. We need a lot of clearance for the Pi Compute module so we can put parts underneath. Let’s look up the matching connectors for the CM4/CM5, what clearances you’ll get, pricing, and the availability from DigiKey.
