Docs/mechanical_BOM.md does not list the ESP32 chip to get.

here is a link to ESP32 Dev: https://www.amazon.com/HiLetgo-ESP-WROOM-32-Development-Microcontroller-Integrated/dp/B0718T232Z

~~Or this one for two: https://www.amazon.com/MELIFE-Development-Dual-Mode-Microcontroller-Integrated/dp/B07Q576VWZ~~

Do not get the second one. It has the wrong number of pins.

It needs to be 19x2 with a pin width space of 0.9". Do not get the 15x2 version or the 19x2 1.0" width version.

Ugh, thanks...

the specs on these seem hard to find but this one seems to meet the needs, 19x2 and ~0.89" pin spacing: ~~https://www.amazon.com/KeeYees-Development-Bluetooth-Microcontroller-ESP-WROOM-32/dp/B07QCP2451~~

UPDATE: from the reviews, it seems that this does not have the autoload and you have to push a button to load on it. Looks like the HiLetGo one is the recommended one.

Most of my boards support the (2) widths of the 19x2 types. I'll be adding this to the next rev of the PCB. I'll be ordering and testing it before I post it.

dwightmulcahy commented 4 years ago

nice. I bought one of the v1 boards that you had...

dwightmulcahy commented 4 years ago

ended up getting this one: https://www.amazon.com/gp/product/B0718T232Z

closing this issue as the PCB/BOM.md lists the need for an ESP32 Dev Kit (0.9" Wide Type).
