All Satellite1 ordered on or after February 17, 2026 include an external antenna for improved Wi-Fi strength. The antenna is required to connect the board to Wi-Fi. If the included antenna is too large for your setup, you can use a smaller antenna with an IPEX connector.
Gently press the antenna's connector onto the connector on the Core board next to the ESP32 chip.
Step 2: Attach the Core to the Hat
Press Firmly!
The pins should protrude through the top of the Hat enough to be felt with your fingertips.
Locate the Raspberry Pi standard 40-pin header on the Hat board. Carefully align the Core board's two rows of pins with the Hat's 40-pin connector, then press the boards together.
Attach a speaker driver of your choice to the Satellite1's amplified 30W JST-XH speaker connector. We recommend a 4-ohm full-range speaker rated to handle up to 30W, but smaller speakers and 8-ohm speakers will also work. Alternatively, you can connect an externally amplified speaker to the Satellite1's line-out/headphone jack.
Step 5: Attach USB-C Power
Use the Correct USB-C Port
If you plug into the USB port labeled "XMOS", you will not hear audio from the Sat1 amplifier.
Plug in to the Hat's USB-C port labeled "CORE/ESP" using the 30 W USB-C power adapter and cable supplied with your dev kit.
On first boot, the blue LEDs will count down clockwise while the device flashes the XMOS audio processor.
