3.1.33：Interface Board

PowerWriter provides PW200,PW300, PWX1 adapter boards.The adapter board introduces a large number of orderly interfaces, facilitating the pin confirmation and wiring during the burning process.

Notes for the PWX1 adapter board:

In order to allow the production equipment to have a more adaptable range of impedance, the PowerWriter X1 comes with an adapter board that provides an additional, 0~100R adjustable impedance resistor, in addition to the output impedance of the X1 equipment, as shown in the figure below.For more information on impedance matching, please refer to this chapter.Impedance

The red frame is for ISP unlocking. If there is no need for ISP unlocking, it will default to the middle position.

The red box indicates the resistance values of the resistors in series with SWDIO and SWCLK.

  • Turn counterclockwise to decrease the resistance.
  • Turn clockwise to increase the resistance.
  • If communication is unstable or signal reflection is severe, increasing the resistance will help improve the situation.
