3.1 Onboard Connectors
Figure 4: Top side connectors
The following connectors are available on the TMC2300-MOTOR-EVAL.
1.
Battery charger connector
: This is a USB-C connector. Connect a 5V charger to it to allow charging
2.
External supply header
: This is an additional supply option. An external stabilized supply with
absolute max. level of 5V can be connected here. This supply is not used for charging. This supply
directly connects to the driver and MCU (the MCU is a 5V-compatible MCU).
3.
UART communication header
: This is a standard 2.54mm pitch header with direct connection to
the MCU. It is required for serial communication with the TMCL-IDE on a PC. Connect a USB-2-UART
converter to it. When using a 5V external supply a 5V-capable USB-2-UART converter is suggested.
Most 3.3V type USB-2-UART converters work as well when using the Li-Ion cell for supply.
4.
Stepper motor connector
: This is a 4-pin JST PH series connector and connects the TMC2300-LA
motor driver outputs to the motor phases. By default the onboard permanent magnet stepper motor
is connected. An own external motor can be connected as well.
Plug/unplug the motor only when
the module is not powered!
All connectors have a pin 1 mark and signal labels at each pin.
