About the DAQ HAT
DAQ HAT is an open source PCB design by MSTRocketDesignTeam, published on GitHub under the AGPL-3.0 license. It is a 2-layer board measuring 146.1 × 144.9 mm, with 20 components from 20 distinct parts.
Other key parts include the DAQ_Module and UA78M09CKVURG3. By type, the board carries 12 connectors, 3 resistors, 2 ICs and 2 capacitors.
It belongs with the robotics & motion and dev boards & breakouts designs in this gallery.
From the project
Evolution of the RDT's Custom Liquid Engine Control Unit!
Future developments may allow for preflight simulations (FEA / CFD of engine, estimated throttling curve, etc.).
