Caravel mvp
About the Caravel mvp PCB
Caravel mvp is an open source PCB design by TinyTapeout, published on GitHub under the Apache-2.0 license. It is a 4-layer board measuring 39 × 54 mm, with 55 components from 23 distinct parts.
Other key parts include the W25Q32JVSSIQ, AZ1117IH-3.3TRG1 and AP2112K-1.8. By type, the board carries 24 capacitors, 15 resistors, 6 connectors, 4 ICs, 2 switches and 2 diodes.
From the project
the minimum necessary to use a Caravel chip (Google MPW or chipIgnite)
This is a sample "minimum viable PCB" for Caravel chips: Google MPW or chipIgnite, including variants for TinyTapeout.
Fork this repo to get a head start on spinning your own Caravel based PCB.
The circuit includes all the critical (required) elements, basically:
power regulation; a clock signal; flash memory, for code; and the chip itself
along with basic passive support (bypass caps...) Full schematic PDF here
