This terminal block expansion hat for Raspberry Pi offers securely and stably fitted connections for your projects.

All GPIO pins are broken out to terminal blocks. The terminal block is labeled with high-quality color silkscreens, clear and durable. Besides, it has onboard level indication LEDs for corresponding pins below the blocks, which allows users to directly view the pin status when operating GPIO so as to conveniently do testing, debugging, and post-maintenance.
