zoe2 HAT
Retired project
zoe2 is retired. This page and the related guides remain available for existing hardware.
zoe2 is a Raspberry Pi radio HAT built around a CC1352P module. It keeps the radio on the Pi rather than on a separate USB stick and communicates through the GPIO UART.
Hardware
- Texas Instruments CC1352P wireless microcontroller module
- Direct connection to the Raspberry Pi primary UART
- External 2.4 GHz antenna connection
- Active-low BSL input on
DIO_15 - Reset and JTAG access
- Power-over-Ethernet-oriented gateway form factor
Host interface
The Pi sees the radio through its primary UART rather than through a USB-to-serial bridge. Applications should use the stable /dev/serial0 alias after the Linux serial console has been disabled and the UART enabled.
Firmware family
zoe2 uses the CC1352P2_CC2652P_other_* firmware target. It does not have the USB modem-control wiring used for Auto-BSL on zzhp, so bootloader entry is manual.
