About the Hello-My-Name-Is-PCB-Badge

Hello-My-Name-Is-PCB-Badge is an open source RP2040/RP2350 PCB design by MitchellStride, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 59 × 31.5 mm, with 75 components from 33 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the RT9080-33GJ5, TPS61040DBV and W25Q64JV. By type, the board carries 28 capacitors, 20 resistors, 5 switches, 5 diodes, 4 ICs and 3 connectors.

It belongs with the wearables and power & battery designs in this gallery.

From the project

#badgelife

This #Badgelife PCB was created to test some circuits for future art PCBs. It also served as a small project to bring to local hardware meetups. Partial assembly was done at JLCPCB.

- I saw someone else's design online using an RGB LED running at 3.3V (below spec). I tried to replicate it, and the LEDs were very flaky and worked intermittently. Experiment failed 😢. - AA boost converter not yet tested; currently using USB power only.
