BASE System User Guide

Getting Started

• Power the Base board via USB-C or plug in a Base Battery
• Turn on the device by pressing the User button
• Connect to the board via a client (official Meshtastic app, web client or CLI)
• The bluetooth pairing code is '123456' (device without display) or shown on display
• To to turn off the board hold the User button for 5 seconds

Device tips

• To flash firmware, double press the Reset button (on side next to USB-C) to enter DFU mode
• Using the web flasher choose the 'muzi Base' device
  • Base Duo and Base Uno share the same firmware, it will auto-detect on boot

Battery Compatibility and Charge Settings

Base boards are designed to work with many battery options to provide flexibility for your specific needs and battery availability in your local region.

Battery selection requirements:

• Capable of receiving 500mA of charge current
• We highly recommend using a 3 pin battery with NTC thermistor (10K,  β = 3435K) for thermal protection.
• Connector is 3 pin Molex PicoBlade (1.25mm pitch)
• Chemistry supported: Li-ion/LiPo and LFP/LiFePO4

There are three solderable jumpers available to configure your system.

• Fast Charge jumper:
  • Default (open circuit) max 500mA charge current
  • Bridge to set 1A max charge current for your Li-ion or LiPo battery
• LFP jumper:
  • Bridge to set charge voltage cutoff for LFP batteries and default 1A charge current
• NTC Bypass jumper:
  • Bridge to bypass all thermal protections on the board
  • You are responsible for ensuring your battery is in the correct thermal operating window
