Product description: Chain Blank - prototyping board for M5Stack Chain - M5Stack U210
Chain Blank is an expansion module from the M5Stack Chain series, designed for users who want to create their own electronics. The front panel features a universal 18 x 18 mm prototyping pad with a 2.54 mm pitch, enabling convenient soldering of through-hole components and the construction of custom circuits. Inside the module are two pre-wired HY2.0-4P connectors , allowing the board to be directly connected to a chain of M5Stack Chain devices without affecting the operation of other modules. When creating your own expansions , you can remove the two 0 Ω resistors responsible for connecting the R1 and R2 communication lines. This allows signals to be output to your own circuits via wires or solder joints, expanding your design options.

The module enables the construction of dedicated interfaces, simple electronic circuits, adapters and custom communication modules.
