Order Development Modules §

To start the hardware development process I first need development modules so I can plan out the interconnections of all the hardware, as well as a platform for me to begin the firmware development process.

In my opinion the best piece of hardware for this type of projec

Pick SMD Components §

• ESP32-S3-WROOM-1- Datasheet

  • I already have 6 of these on hand, they have 16MB Flash, 384kB ROM, 8MB SRAM. This is almost assuredly an overkill amount of memory. Once I build initial models, I can purchase models with reasonable amounts of memory for half the cost. The development board Im using only has 4MB Flash 2MB PSRAM, the equivalent WROOM module is $4.74vs$5.96 (I thought it was more expensive).
