About the MIO-Blind-Bot PCB

MIO-Blind-Bot is an open source PCB design by GuruManoharGuptaBaratam, published on GitHub. It is a 2-layer board measuring 75.7 × 125 mm, with 6 components from 6 distinct parts.

Other key parts include the LM2596 (3.3v).

It belongs with the power & battery, wearables and sensors designs in this gallery.

From the project

Hardware design (KiCad) for MIO-Blind_BOT — the power and interconnect board for MIO, a wearable dual-ESP32 assistive system for blind users. Integrates battery management, buck regulation, pan-tilt servo control, IMU, and TFT status display, with Bluetooth audio feedback via earbuds

Custom hardware design for MIO — a wearable assistive device for blind and low-vision users

This repository contains the complete PCB hardware design for MIO, a dual-ESP32 wearable assistive device. The board serves as the central interconnect and power-management platform of the system, tying together the compute modules, motion sensing, camera pan-tilt actuation, display feedback, and battery power delivery into a single wearable-ready design.
