The tetra hardware is based on the Broadcom BCM23550 (referred to as java in the device tree) chipset.
Front
The front of the PCB is covered by a flexible PCB antenna used for NFC. This is connected to the PCB via a U.FL connector.
Removing the NFC antenna reveals the Broadcom SoC and on its left a shield on top of the memory.
The shield with a QR code is covering the BCM43341 Bluetooth/WiFi chip.
The unmarked chip on the top left is most likely the bcmpmu (Broadcom Power Management Unit).
Back
The back of the PCB has testpoints, pogo pins and space for an unpopulated connector.
