"Original" STorM32 Boards
At present, board versions v6.x are supported (v0.17/v1.0, v1.1, v1.2, v1.3x, v2.4, v3.3, v4.1 boards are not supported).
The STorM32 boards offer two types of NT bus ports, the NT and NT-X ports. They both are different from the NT bus connectors on the NT modules in that they have swapped Rx, Tx pins.
Comment: The Rx, Tx pins of the NT and NT-X ports on the STorM32 board must be connected to the Tx, Rx pins on the NT modules.
Comment: The v6.2 STorM32 board has no motor drivers on-board, i.e., NT motor modules are needed in addition.
In addition to the boards shown here, also other variants exist, such as e.g. micro versions.

Comment: This board has no motor drivers; NT motor modules are thus mandatorily required.
