Witty Pi 5 can define your Raspberry Pi’s on/off sequence, trigger power actions based on temperature or voltage thresholds, and help reduce overall energy consumption in remote or battery-conscious projects.This fifth-generation Witty Pi is the first in the line to comply with the Raspberry Pi HAT+ specification. As a Mode 1 Power HAT+ board, it can deliver up to 5A to the Raspberry Pi and connected peripherals, while its onboard DC/DC converter accepts up to 30V DC input.It supports Raspberry Pi models with a 40-pin GPIO header, including A+, B+, 2B, Zero, Zero W, Zero 2 W, 3B, 3B+, 3A+, 4B and 5B. For Zero-series boards, you’ll need to solder a 40-pin header first for a reliable connection.The firmware and software are open-source for developer customisation, with firmware written in C using the pico-sdk and software written in C. Firmware updates are handled via the BOOTSEL button and USB boot mode, and the board can emulate both a USB flash drive and a USB serial device for configuration, logs and debugging. Coin cell battery is not included.Features:Real-time clock: High-precision RTC with an accuracy of ±3.8 to 5 ppm.Temperature sensor: Dedicated temperature sensor with 0.0625°C resolution.DC/DC converter: Onboard DC/DC converter that accepts up to 30V DC input.Ideal diodes: Two “ideal” diodes that isolate VIN and VUSB.Microcontroller: RP2350 MCU with an external 16MB flash memory.ID EEPROM: Compatible with the HAT+ specification.Power sequencing: Can define the on/off sequence of your Raspberry Pi.Threshold actions: Can perform power on/off actions based on temperature or voltage thresholds.Lower power operation: Can significantly reduce overall energy consumption.Developer friendly: Firmware and software are fully open-source for modification and adaptation.Easy firmware updates: Hold BOOTSEL while connecting USB, then drag and drop the compiled .uf2 firmware file.USB tools: Emulates both a USB flash drive and a USB serial device for configuration, logs and real-time monitoring.Specifications:HAT standard: Raspberry Pi HAT+ specification.Power HAT+ mode: Mode 1 Power HAT+ board.Output current: Up to 5A current to Raspberry Pi and its peripherals.Raspberry Pi compatibility: All Raspberry Pi models with a 40-pin GPIO header, including A+, B+, 2B, Zero, Zero W, Zero 2 W, 3B, 3B+, 3A+, 4B, and 5B.Zero-series requirement: For models like Zero, Zero W, and Zero 2 W, you will need to solder a 40-pin header onto the board beforehand to ensure a reliable connection with Witty Pi.RTC accuracy: ±3.8 to 5 ppm.Temperature sensor resolution: 0.0625°C.DC input: Up to 30V DC input.Microcontroller: RP2350.External flash memory: 16MB.ID EEPROM: Compatible with HAT+ specification.Firmware: Written in C using the pico-sdk.Software: Written in C.Software and firmware: Fully open-source.Software installation command 1: pi@raspberrypi:~ $ wget https://www.uugear.com/repo/WittyPi5/wp5_latest.debSoftware installation command 2: pi@raspberrypi:~ $ sudo apt install ./wp5_latest.debFirmware update mode: Hold the BOOTSEL button while connecting the USB cable to make the RP2350 enter USB boot mode and present itself as a virtual USB drive.Firmware file: Drag-and-drop the compiled .uf2 firmware file to flash it.USB emulation: USB flash drive and USB serial device.Battery: Coin cell battery is not included.Customer support: Supplier forum.User Manual: Available from the supplier.Ideal for scheduled Raspberry Pi projects, remote deployments, data loggers and systems that need controlled shutdowns or reliable timekeeping. **Product Type:** Raspberry Pi HAT ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDZtECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--fb9b5ff1a28b9f4ee9fdc7f920ba460780010361/6449-01.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDadECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--3d7049fd098b802d69e69cc44eaaf54b469e13e2/6449-06.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDbtECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--4795bd62d4256dbcbc13f102867bd94661fc3d51/6449-00.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDcdECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--c4dbc4dc6b1862f8ae413bf3c50b5897aae878c0/6449-02.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDdNECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--0a744b512247a39ebebd94caa18ce2a7dafc5d95/6449-04.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDetECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--1e9ebec0aa487935eccc0553ef847e10d949f36e/6449-05.jpg) - [Image 7](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDe9ECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--c4c979aad3fbc41c0c5d0c29a43451ebcfe2f640/6449-03.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
