Meet EdgeS3[D]
EdgeS3[D] is a complete ESP32-S3 development board on a removable M.2 B-Key module. Plug it into a carrier PCB, pull it out and reuse it in your next project. It has an onboard antenna and a u.FL connector, switchable from your code, an I²C fuel gauge for battery monitoring, and eight extra IO from its onboard expander.
![Series[D] features: Both antennas. One board. · Switch in software. · Know your battery.](https://unexpectedmaker.com/images/product-content/series-d-features-edges3d.gif)
NOTE The onboard antenna is selected by default, so you never need to worry about the RF switch being in a bad state, or the ESP32-S3 getting damaged if you forget to plug in an external antenna.

Note: EdgeS3[D] is only available in a 2MB QSPI PSRAM version right now. There may be an 8MB OPI PSRAM version later, depending on silicon availability.
Which B-Key M.2 Connector will I get?
The M.2 connector I use on the EdgeS3[D] Carrier PCB, and that I ship here is the Amphenol MDT275B03001, which is a side entry B-Key connector that is 2.75mm in height, and has the EdgeS3[D] sitting 1mm off the PCB.
Available at Mouser and other online distributors.
Note: EdgeS3[D] is not compatible with a M.2 slot in your computer. Please don't attempt to insert it "just to see".
