Be the first to know when the Pwnagotchi Hat is available. No spam, just a one-time notification.
The Pwnagotchi Hat is an all-in-one expansion board designed for the Raspberry Pi Zero, purpose-built for Pwnagotchi deployments and wardriving. It integrates a UPS, dual-band AC WiFi with monitor mode and packet injection, GPS with PPS support, a USB hub, and a hardware RTC — all in a single stackable board.
An optional 18650 battery and antenna backplate makes field deployment effortless, turning your Pi Zero into a fully self-contained wireless intelligence platform.
Key Features
UPS & Power Management
Charge + 5V output for Pi Zero
- Simultaneous charging and 5V output to Pi Zero
- JST 2.0 connector for LiPo / Li-ion polymer battery
- 18650 battery support via optional backplate (up to 4 hours runtime)
- Battery status readable via I²C
- Dedicated Pwnagotchi plugin provided
- Stable power for uninterrupted field operation
GPS with PPS
GPS + BeiDou or GPS + GLONASS
- Dual-constellation: GPS + BeiDou or GPS + GLONASS
- Active GPS antenna support
- PPS (Pulse Per Second) output for precision timing
- Connected via USB Serial — Pi Zero UART stays free
- Wardriving location logging out of the box
AC Dual-Band WiFi
Same chip as ALFA AWUS036ACM
- MediaTek MT7612U chipset (ALFA AWUS036ACM equivalent)
- Monitor mode and packet injection supported
- Dual-band: 2.4 GHz + 5 GHz 802.11ac
- Bluetooth with onboard antenna
- Ideal for Pwnagotchi AI training and wardriving
4-Port USB Hub
GPS + WiFi internal · 2 ports exposed
- 4-port internal USB hub
- GPS and AC WiFi each occupy one internal port
- Remaining two ports exposed as USB-A and USB-C
- Expand with additional USB peripherals
RTC with Rechargeable Battery
Timekeeping + scheduled tasks
- Onboard rechargeable RTC battery and charging circuit
- Accurate timekeeping without network sync
- Supports scheduled tasks: timed power on/off
- Ideal for automated field deployments
18650 Battery & Antenna Backplate
Stackable field deployment
- Dedicated backplate for 18650 battery mounting
- Antenna mounting points for external antennas
- Stackable design — attaches directly beneath the Hat
- Enables fully self-contained portable deployment
ℹ️ GPS is connected via USB Serial, so the Pi Zero's hardware UART remains available for serial console access — no conflicts with your existing setup.
