QFN-12 to SOIC8 replace

[vakuliniv]

Dear author, in your project "Legacy_stepper_motor_analyser" you used current sensors ACS70331EESATR-2P5B3 (x2 QFN-12 chip ). Can you make light redesign of the board and add place for SOIC-8 version of current sensors (ACS70331EOLCTR-2P5B3), or fully change places ( x2 QFN-12 to x2 SOIC-8)? This is problem for me to find sensor in QFN-12 chip with adequate price :( The SOIC-8 version is widely presented in available stores. I'm sorry, but I haven't enough time to deal with Kicad now :(. Alas, migrate to Raspbery PI is not acceptable variant too. Best regards

Hello vakuliniv,

Have you looked at the new design? It uses a different package of the same IC.

Hello, zapta. Yes, I saw your new design :) But it was designed for Raspbery Pi :( This is not entirely convenient for me ... I would like to use exactly STM32 version by some reasons. Therefore, my request remains valid. I hope, it will be easy for you to made this changes.

Hi vakuliniv, sorry but I don't have an SOIC version of the legacy design and I don't maintain it any more (that's why I renamed to 'legacy').

Hello, zapta. I had to master the basics of the KiCad and make changes to the design myself. Now legacy project has board with SOIC-8 footprint. Are you need this version?

Hi vakuliniv, thanks for the offer. I prefer not to touch the legacy version and focus on the new design because it's based on the Raspberry Pico (a superior MCU) and a less expensive bare TFT that also allows a more compact case.

Good luck with the project. It's a lot of fun.
