Hi everyone i'm using a development board lopy4 and i wanted to have the PCB design to know the capacities and resistors that are linked to the Pins i have founded the pcb design for the universal OEM baseboard is it the same ?? please i need your help

Please include the following information when submitting a bug report:

• The Pycom board you are using (e.g. WiPy 2.0, LoPy).
• The firmware version you are using. You can get it by executing the following Python code at the REPL:

  import os
  os.uname()

  The output will look similar to this:

  (sysname='LoPy', nodename='LoPy', release='0.9.4.b1', version='bc42ea7 on 2016-11-14', machine='LoPy with ESP32')

• Exact steps to cause this issue
  1. First I did this...
  2. Then, I did that...
• What you expected
  • e.g. I expected abc to xyz
• What happened instead
  • e.g. Instead, I got zyx

Thank you!

Hello leila111111!

Please refer LoPy4 datasheet minimum required circuit on page 27: https://docs.pycom.io/gitbook/assets/specsheets/Pycom_002_Specsheets_LoPy4_v2.pdf

As shown in the minimum required circuit decoupling capacitors are not required. In case if power supply wires too long, you can place close to power pins a ceramic or electrolytic capacitor in range 10uF .. 470uF

OEM modules require external voltage regulator and decoupling capacitors
