⚠️ Looking for V1? The first version of the Cyberboard is available in the v1 branch, but be warned: it doesn't work. V2 is a complete redesign with proper functionality.

• STM32WB55CG microcontroller with Bluetooth support
• Raspberry Pi Pico form factor for compatibility
• IMU and Barometer - ICM-42688 (6-axis) and BMP580 pressure sensor for environmental/motion sensing
• Battery charging with BQ24072RGTR IC and solder pad for 1S LiPo
• Buck-Boost converter (TPS631000) for efficient power management
• Multiple Status LEDs for visual feedback
• USB-C connectivity
• Ceramic Bluetooth antenna with impedance matching
• SWD test points on the bottom for easy programming
• 4-layer PCB design with optimized RF layout and routing
• Panelized design for cost-effective manufacturing

Designed in KiCad with attention to RF design, power management, and sensor integration. The board features a 4-layer stackup (SIG/GND/PWR/SIG) with optimized routing for the Bluetooth antenna and sensitive analog signals.

The 4-layer stackup (SIG/GND/PWR/SIG) provides optimal signal integrity and power distribution:

Layer 1 (Signal):

Layer 2 (Ground):

Layer 3 (Power):

Layer 4 (Signal):

Front:

Back:

This project uses:

• KiCad
• Blender for 3D renders
• Hack Club Blueprint

• CyberCard – A Cyberpunk themed NFC hacker card
• Ember – USB-C PD Powered Hotplate
• Trace – An ruler for engineers
• Athena – A flight controlelr with a triple MCU architecture
