CB1 heatsink

What is it? Big Tree Tech Manta boards are a fully integrated alternative to the Raspberry Pi by using their CB1 module. There are two versions of Manta boards. The first one has 4 drivers (M4P) which is now being replaced by the M5p 5 driver and the second one has 8 drivers (M8P). The powerful CB1 Raspberry pi alternative features a Quad-core 64-bit ARM Cortex-A53 with a 1.5 GHz processor and 1 GB DDR3 RAM. Together with the optional CB1 Heatsink provides for an excellent platform to run Klipper on the most demanding printers.
