Hybohat Development Board

Update R3

Correction was made for Arduino Nano module. ESP32 module was adjusted for use with male pin header modules.

Introduction

The Hybohat module was designed as a simple, passive way to interconnect the User I/O connector of the iLidar to a variety of common development boards. These are:

• STM32F4 Discovery
• Arduino Uno & Leonardo
• STM32F429ZI Nucleo
• ESP32
• Raspberry Pi & Pi Zero
• Arduino Nano (and STM32F103 Nano form-factor)

Concept

The board can be envisioned as a large cross-bar switch with each dev board's I/O ports conected to a bus. In case a development board has multiple ports of the same time, the desired port is selected with jumpers in the three vertical columns labeled

• SPI SEL JUMPERS (JP4NN1, JP4DD1)
• I2C SEL JUMPERS (JP2NN1, JP2DD1)
• ASYNC SEL JUMPERS (JP3NN1, JP3DD1, JP2EE1)

One end of this bus is connected to iLidar's User I/O connector by the jumper block labeled: I/O MODE SELECT (JP6) Note that only one mode can be operational at a time.

The other end of the bus is terminated in four connectors which can be used to probe and monitor the I/O:

• I2C (J2)
• SPI (J3)
• ASYNC (J4)
• TRIG (J5)
