MCP23017 + ESP32
Budget: ₹600 – ₹1,500 INR
I have design ready which includes ESP32 along with some I2C peripherals.
Existing design includes PCF8574 IO expander which is based on I2C. Due to some technical reason It is required to replace PCF8574 with MCP23017.
This is a part of the ongoing project. So for the moment my requirement is to do replacement of PCF8574 with MCP23017 (Will hire for next stages and other projects too only if work is appropriate). So for this replacement you have to do following...
1. Make required changes in existing schematic with all necessary components (such as strong pull-up/pull-down).
2. Do layout changes according to the updated schematic(as per step 1). Layout changes has to be done as minimum as possible, so that existing layout won't change much.
Note:
- Existing design has been done in PSPICE.
- You must have knowledge of ESP32 and I2C IO Expander(Specially MCP23017 & PCF8574).
