Next General Meeting
BotPMU
When: Wed February 25 at 7PM West Coast Time
By featured Homebrewed Roboticist: Nathan Lewis
The last decade has seen widespread adoption of the USB-C connector and the USB-C PD (Power Delivery) protocol. The hobby robotics space has been mostly insulated from USB-C PD up until the introduction of the Raspberry Pi 5, which (in)famously requires a non-standard USB-C power adapter to function completely. This renders the RPi5 unable to be used with the majority of USB-C PD power banks available on the market.
Our own Nathan Lewis has been developing a USB-C power supply and battery management controller called the “BotPMU”, which provides USB-C PD 3.1 ports compatible with the Raspberry Pi 5’s non-standard profile, as well as any standard USB-C PD devices, delivering up to 240 W. The BotPMU also provides a dedicated DC-out port which can be used to directly tap the battery to power motor drivers and other high current devices.
Nathan will be giving a brief technical overview of developing with USB-C PD and doing a deep dive into the development process of the BotPMU and the features it provides to hobby robots.

Next Builders' SIG Meeting
When: Wed February 18 at 7PM West Coast Time
The HBRC SIG (Special Interest Group) is a random access group; that is a loosely organized discussion of homebrewed robots. Bring your robot, show it off, ask questions, and generally hang out with others who enjoy robot-building as a pastime and/or profession. From beginner to expert, if you are interested in robotics, please join us.
