Board carrier
About the Board carrier
Board carrier is an open source PCB design by mck1117, published on GitHub under the MIT license. It is a 2-layer board measuring 40 × 36.5 mm, with 18 components from 12 distinct parts.
Other key parts include the TJA1051T-3, LM78M05_TO252 and f042_wideband_module. By type, the board carries 10 capacitors, 3 ICs, 2 diodes, 2 resistors and 1 connector.
From the project
Wideband O2 sensor controller on a postage stamp. Contains all the analog and digital control logic to handle a Bosch LSU 4.2, 4.9, or ADV sensor.
Wideband O2 sensor controller on a postage stamp. Contains all the analog and digital control logic to handle a Bosch LSU 4.2, 4.9, or ADV sensor.
Intended to either be mounted on an ECU as a module, or on boardcarrier` to run standalone.
Stacks under boardmodule`, has 5v regulator, CAN tranceiver, etc so that the module can exist standlone.
