Which family of chips i should look into for lightweight and custom application?
need help guys - so yst i had my hackathon in which i presented a electronic based model were i used esp32 as micro controller but asper a judge instead of a protocol which is using wifi i should use poe or powerline protocol and go with more lightweight , power efficent chip rather than esp32 which was very powerful for that task , till now i have justed build my projectsa round esp32 and arduino , So which family of chips i should look into for lightweight and custom application . I want a family in which the code remains the same for all chips but we can choose which chip with how many pins to be used . Can anyone suggest ?
Solution
PoE should work as well. It might be easy to integrate while installation and is a fully wired method unlike other popular wireless IoT.
The software-stack and processing you need in PoE case might get complex and not all MCUs come with ethernet peripheral. For example, say RA6M2. It comes with ethernet MAC (exposing RGMII lines) and an external PHY chip say DP83867 will be required to further down connect with the RJ-45 port having twisted pair lines.
Also, the POE requires it's set of chips - usually a rectifier IC and PoE PD IC for handshaking to extract power from the twisted pair lines (ex: https://ww1.microchip.com/downloads/en/Appnotes/AN3533-PD70210AAL_and_PD70211_System_Layout_Guidelines.pdf)
System may look like:
[Sensors] --> SPI/I2C--> [MCU]-->RGMII-->[PHY]-->[RJ-45] <---- [PoE Connector]

Power <--[PoE PD]<-- [Rectifier]<--
