Foot Pressure Measurement using Hexabitz

►Project Tools

We'll list the tools used in this project:

1) Hexabitz Load Cell Sensor Module (H26R0x):

H26R0x is a load cell (strain gauge) sensor interface module [2].

2) Hexabitz Mini USB-B to UART Converter (H1AR2x):

H26H1AR2x is a Mini USB-B-to-UART bridge module based on FTDI FT230XQ-R and STM32F0 MCU. It provides both power and communication through a virtual COM port [3].

3) User Tools Kit:

This kit includes the tools that are essential for programming, debugging, and powering Hexabitz modules.

• FTDI USB to UART Serial cable:

The 4-pin USB 2.0 to UART serial cable is an indispensable tool for Hexabitz development! It incorporates FTDI’s USB to UART interface [3].

• Hexabitz BitzClamp:

Hexabitz BitzClamp is a modified Kelvin current clamp soldered to two 2.56 mm-pitch male jumper wires [4].

• STLINK-V3MODS Programmer (H40Rx):

H40Rx is a programmer module which contains STLINK-V3MODS stand-alone debugging and programming mini probe for STM32 microcontrollers (Hexabitz modules and other MCUs) [5].

• E-Z-Hook Programming Kit:

Instead of soldering SMD connectors there, you could use a nice off-the-shelf E-Z-Hook kit that we assembled for you [6].

4) SEWHACNM Single Point Load Cell (AB120-30kgf):

A Korean anodized aluminum load cell with IP65 protection and 30kgf load capacity [7].

► Steps for Implementing the Project

We'll mention step-by-step instructions from designing to implementing this project:

1. Planning the array and assembling the hardware:

First, we prepare the project parts and plan our array design by aligning the three modules side by side. Then we solder the modules together using Hexabitz Fixture.
