RaspTank Metal is an upgraded version of RaspTank, with structural components replaced from acrylic to aluminum alloy. Compared with RaspTank, the biggest advantage of RaspTank Metal is that it is easy to assemble and saves enough time.

Compared to the previous version, the main changes in RaspTank Metal are:
1. The battery holder is installed at the bottom and uses a dual position integrated battery holder, which is more reliable and easier to assemble.
2. We have redefined the Robot HAT, which integrates an 8.4V lithium battery charger that allows you to charge the battery directly through the USB-C port on the Robot HAT.
3. Robot HAT has been upgraded to V3.2 version, which has higher power compared to previous versions. This is because we have designed two sets of DC-DC circuits for Raspberry Pi and other peripherals such as servos, LEDs, sensors, etc., so that there will be no phenomenon of Raspberry Pi restarting due to insufficient power supply.
4. In Robot HAT V3.2, we replaced mechanical switche with MOSFET, which allows it to pass larger currents. PS: The mechanical switch still exists, but it is only used to trigger MOSFET.
5. It is fully compatible with Pi5 and backward compatible with Pi 4B/3B/3B+/2B.
6. The position of WS2812 light bars have been changed.
7. We have carefully re-written the tutorial and code, which is better than any previous version.

Raspberry Pi board is NOT included in this kit !
