Shared Project:
This Pi-computer project is created by Peter Misenko. It is a compact, palm-sized computing device featuring an integrated keyboard made from tactile push-button switches, a high-quality TFT IPS display, and a Raspberry Pi Pico module.
The primary objective of this project was to minimize the number of external components, leveraging the full potential of the Raspberry Pi Pico’s capabilities. Key components include a filter capacitor for the optional LoRa module, two MOSFETs, and three resistors to drive the speaker and TFT backlight. Apart from the connectors, switches, and sub-modules, the external circuitry is kept to a bare minimum.
Key Features:
- Compact dimensions: 100 x 65 x 8 mm, designed to be as small as possible.
- Minimal external components to optimize the use of the Raspberry Pi Pico’s features.
- Auxiliary USB-C port, used exclusively for power input.
- Accessible boot button for easy programming and recovery.
- Bonus feature: flashing eyes powered by an internal LED.
- IPS 240×240 display with support for at least three different screen types.
- Integrated speaker for audio output.
- Free GPIO header for additional expansion and customization.
- Reset button for quick recovery and system reboot.
- Power switch that controls the internal buck-boost converter for efficient power management.
- Optional RFM95 LoRa radio module for long-range wireless communication.
