HydraBus Team have participated to Riscure, RHME2 and we are 1st !!
Thanks to all participants and Riscure for those amazing challenges

HydraBus boards are now back in stock (with same price as before) and new features:

• New PCB v1.0 Rev1.2+ (add capacitor for MicroSD +3V3 for even more stable supply for big microSD/SDIO …)
• Replaced MCU STM32F405 by STM32F415 with hardware cryptographic acceleration for:
  • AES 128, 192, 256
  • Triple DES
  • HASH (MD5, SHA-1), and HMAC
• Added Clear laser-cut acrylic case with screws

HydraESP32 HydraBus v1.0 Shield for ESP-WROOM-32 V1.1 Rev1.0 is alive

This new version allow to measure ESP32 power consumption (and/or manage power ON/OFF of ESP32 with any MCU…)
This version can be fully managed using HydraBus STM32 MCU
For more details (BOM, Eagle board …) see
OSHPark link: https://oshpark.com/projects/dgKJqznH
GitHub link: https://github.com/bvernoux/hydraESP32

This 1st part is mainly how to connect  FTDI C232HM DDHSL-0 to ESP32 DevKitC (also called ESP32-CoreBoard V2)

For more details on JTAG /GDB /ESP32 OpenOCD see https://esp-idf.readthedocs.io/en/latest/api-guides/jtag-debugging/index.html

HydraBus Shield / Breakout board for ESP-WROOM-32 new version 1.1(rev1.0)

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.

• New features versus previous version V1.0 Rev1.1:
  • Added LDO (TPS73633DBVR SOT23-5) to convert 5V(VUSB) to a clean VCC (+3.3v) for ESP32 and which can be enabled by an HydraBus Pin or with a JUMPER on J7 (which connect +3.3V from HydraBus to EN of the LDO)
  • Added VCC connector in order to measure ESP32 current/power consumption (if not used to measure current just add a JUMPER on VCC to power the ESP32)
  • Added J6 connector to have access to ESP32 SPI FLASH IOs (now all pins are available)
• This shield can be used only on bottom of HydraBus board (in order to use other shields on top of HydraBus)
• 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)

New feature NFC sniffer ISO14443A real-time infinite trace mode:

For more details see:

Now HydraESP32 shield is alive
See a simple test (to communicate with ESP32 using UART) by wiring ESP32 UART RXD0/TXD0 pins respectively to HydraBus PA9(UART1 TX)/PA10(UART1 RX) and by forcing EN to 3v3
(just plug ESP32 EN on GND then remove it / connect it to +3V3 after bridge mode is enabled)
It is recommended to use latest HydraBus firmware hydrafw v0.8 in order to use UART bridge @115200 bauds 8N1
See asciinema video:

For information we can also interact with ESP32 during bridge mode by connecting a 2nd MicroUSB connector on HydraBus in order to have an other terminal to interact with ESP32 I/O for example to set EN pin to +3.3V or GND … (or even to test different boot mode / communication …)
