zoe HAT
Retired project
zoe is retired. This page and the related guides remain available for existing hardware.
zoe is a Raspberry Pi radio HAT that connects its wireless module directly to the Pi's GPIO UART. It was designed as a compact base for a dedicated home-automation gateway, with optional real-time-clock and power-over-Ethernet configurations.
Hardware​
- Ebyte E18-series radio module
- Direct connection to the Raspberry Pi primary UART
- BSL, reset and debug access on the board
- Optional I²C real-time clock
- Lite, RTC and PoE kit configurations
Because zoe predates zoe2 and uses a different radio generation, firmware images are not interchangeable between the two boards.
Host interface​
The radio uses the Pi's TXD0 and RXD0 pins. Raspberry Pi OS must release the primary UART from the serial console before host software can communicate with it. The RTC option, when populated, appears on I²C address 0x68.
