HydraBus Shield / Breakout board for ESP-WROOM-32.
This shield can be used with or without HydraBus board, you can even cut HydraBus specific right side (on the line) to have a tiny ESP-WROOM-32 breakout board.
This shield can be used on top or bottom of HydraBus board (you just need to solder ESP-WROOM-32 on top or bottom of the shield)
The HydraBus board is a small (60mm x 37mm) and low cost, multi-tool extensible board with STM32F405 Cortex M4F 32bits MCU @168MHz with a fully open source firmware hydrafw and full online documentation hydrafw wiki
The ESP-WROOM-32 is a low-power 32-bit 240 MHz dual core MCU Wi- Fi+BLE combo module that highly integrates TCP/IP network stacks, 12- bit ADC and HSPI/SDIO/UART/PWM/I2C/I2S interfaces. See ESP32 Overview, ESP-WROOM-32 link/info, Espressif Products Overview including ESP-WROOM-32 PDF
Design based on official esp_wroom_32_datasheet_en.pdf (August 8, 2016)
The board has been tested (mainly UART with bridge mode of HydraBus/HydraFW) with an ESP-WROOM-32 soldered on bottom side and all work fine
There is only a typo on silkscreen on bottom side at left of IO15 which is labelled GND instead of IO13
See new version HydraESP32 HydraBus v1.0 Shield for ESP-WROOM-32 V1.1 Rev1.0 which fix that and improve a lot this breakout board
