Bit Trade One GPIO Stack Expansion Board for Raspberry Pi [Assembled]

Up to 5 expansion boards can be connected to one raspberry pie at the same time by using the product.
Also supports external DC power supply.
It can escape from the unstable USB power supply and supply stable power to all boards including Raspberry Pi.
By freely combining various expansion boards, the possibilities of IoT devices will expand further.

Connect up to 5 expansion boards at the same time!
Equipped with 5 slot GPIO pins, up to 5 phat size expansion boards can be connected to Raspberry Pi at the same time.
Two of the slots are compatible with HAT size expansion boards, and up to five HATs and three pHATs can be expanded.
Let's further evolve your Raspberry Pi with the combination of expansion boards.
* It may not be possible to connect depending on the shape of the expansion board used.

Raspberry Pi or Raspberry Pi Zero can be installed!
Normal Raspberry Pi and even smaller Zero can be connected.
It is also possible to use the shutdown / reboot switch in Zero WH.
(Pin header soldering is required to use the switch in 3B)

DC5V can be supplied to Raspberry Pi and pHAT / HAT!
It is possible to supply power to the Raspberry Pi body and all expansion boards from the DC connector on the stack expansion board board.
You can safely conduct experiments with stable power.

Grove system * (I2C / UART) compatible connector installed Grove system * (I2C / UART) compatible connector installed.
It is also ideal for prototyping IoT systems because it is designed to take advantage of expandability, such as the use of servos, sensors, and actuators compatible with commercially available Grove systems.
