ESP32-S2 Stick

After designing the nRF PRO I decided to continue using the form factor and add a more capable MCU as the ESP32-S2 that has BLE and Wifi with a lot of Memory for the app and data.

It is a breadboard-compatible development board featuring the ESP32-S2 series of SoC, Xtensa® single-core 32-bit LX7 microprocessor 4 MB flash and optional 2 MB PSRAM in chip package 26 GPIOs, rich set of peripherals such as UART, SPI, I2C, TOUCH, DAC, ADC, and USB, a 2x2mm SK6812 RGB serial LED and a 0603 SMD blue LED. USB-C connector, castellated holes for low-profile integrations, and an onboard PCB antenna.

I have been using this board for all my projects as it's easier to add to all my current and old projects such as the display-Array, the Cistercian Display, and the Dynamixel Configurator.

This board is very versatile as I have been able to use it easily to test any idea that I have in a protoboard before adding it to a custom PCB, also is easy to add to any new project and not having to place all of those components and having to RF match the antenna every single time. The dimensions are efficient and I love how it looks as it's a very thin PCB.

The board has enough pins with the correct peripheral in hand to accommodate to any project you may have.

Lately, I have been using the services ofPCBWayfor my projects as they have awesome customer support and great quality PCBs, I really love how they do the castellated holes for my boards in a couple of days.

Let me know in the comments below how would you use this board or any project idea that you would like me to explore using this board. If you need more info go to my GitHub.
