Prototype Expansion Board V2 Breadboard DIY Module Electronic Component Bit

Feature: 1. The expansion board comes with chip, which can be externally connected to 4.75-12V to power the bit. 2. All pins and power supplies of the bit development board have been led out to the middle row of the expansion board. 3. The components can be soldered directly on the expansion board, or the circuit can be connected through the 400‑hole breadboard . 4. The extended area is connected by double-sided PCB via holes, components can be soldered on both sides, and there are patch pads on the back IO, which is convenient for flying line connection. 5. A 400‑hole breadboard is placed in the lower part to facilitate experiment expansion.
