BaSHi-SM-1
About the BaSHi-SM-1 PCB
BaSHi-SM-1 is an open source PCB design by kiu, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 48 × 23 mm, with 22 components from 16 distinct parts.
Other key parts include the AP63205WU, 74LVC1G07 and CMT8021N1L. By type, the board carries 8 capacitors, 5 connectors, 3 ICs, 2 diodes, 2 resistors and 1 fuse.
From the project
Bidirectional adapter for Sniffing Home appliances (isolated)
Hajo gave a talk on hacking home appliances at the 39C3. That talk inspired me to build a simple, isolated, bidirectional D-Bus adapter to make tinkering with these devices easier.
In non-isolated mode, the ESP32 is powered by the home appliance. Both jumpers must be shorted. This mode is intended for standalone operation. Do not connect the ESP32 USB port while BaSHi is connected to a home appliance.
