Description
SKR V1.4 and V1.4 Turbo boards have an exact size of 110 x 85mm (102 x 76mm between holes). Their architecture is ARM Cortex-M3 (CPU) and they can be powered interchangeably at 12V and 24V (5A-15A).
They have a connector for Wi-Fi modules ESP-01S, can use different communication modes for their drivers (SPI, UART and STEP / DIR) and support X, Y, ZAM, ZBM, E0 and E1 motors.
The only thing that differentiates the SKR V1.4 electronics from the V1.4 Turbo is that it has a superior microcontroller. In the V1.4 model you can find a 100 Mhz ARM Cortex-M3 micro, while in V1.4 Turbo the micro it presents can reach frequencies of up to 120 Mhz. This is certainly a remarkable 20% increase in process speed, which is no small feat.
