@Ari Wasch

BMS

  • Helped assembly LVDS and science board

  • Met with @Abdul Haseeb to work on arm controller

  • Meet with Josh to start working on Rev 3 BMS

  • Support testing LVDS/Science

@Chealsie Bains (Deactivated)

BLDC

Solar

Any update on BLDC layout?

 

Ethan

PDB

Any update on getting started with PDB?

 

@Farris Matar

PDB/BMS

  • Went in to test PDB:

    • 5V buck converter is bust - cannot reliably assemble buck IC (QFN package) without shorts, blew 2 ICs as a result. Due to stock shortages, this circuit will need to be completely redesigned in the next revision

    • 17V buck converter: Was able to turn the circuit on, but the output was just the same as the input. It turns out the feedback resistors were calculated wrong - this could allow the circuit to be reused in the next revision if the circuit works, only the ICs need to be salvaged as all the other parts can be replaced

  • Finish layout design review guide

  • Try to fix PDB 17V buck converter (requesting someone’s help with this as I won’t be able to go to the bay this week - please message me if you’re able to help)

  • Plan a call with Ethan to go over scope for new revision of PDB

@Ivan Lim

Science

  • Science/LVDS assembly on Saturday and Monday

  • Test Science and LVDS
