sEMG-DAQ is a wearable 6 channel data acquisition unit for capturing surface electromyographic (sEMG) signals from human arm muscles using SJ2-3593D jack connectors while conditioning, digitizing, processing and transmitting them as sEMG data to an external AI accelerated board through an SM12B-SRSS IDC connector where AI models are run for various applications including robotic control, muscle signals medical assessment and gesture recognition. The board leverages an INA125P instrumentation amplifier together with filter stages utilizing LM324QT op-amps for conditioning and an STM32G4A1VET6 microcontroller for the digitization, processing and data transmission of the signals. Since AI models can only be as good as the data, the design of such a DAQ is necessary to ensure clean, reliable and real-time data for AI applications requiring sEMG data. The board also has USB-FS and JTAG to cater for debugging. The power (5V) is fed through a screw terminal and is regulated by two LDK320AM LDO regulators to offer 5V, 3.3V and 1.8V to meet the requirements of various components on the board.

This project involves designing a complete schematic for a robotic arm controller based on the ESP32-C3 microcontroller, specifically using the ESP32-C3-MINI-1-N4 module. The design features a dual power input system and comprehensive power management, motor control, I/O interfaces, and status indicators—all implemented on a 2-layer PCB. Key Specifications: Microcontroller: • ESP32-C3-MINI-1-N4 module operating at 3.3V. • Integrated USB programming connections with reset and boot mode buttons. Power System: • Dual power inputs with automatic source selection: USB-C port (5V input) and barrel jack (6-12V input). • Power management using LM74610 smart diode controllers for power source OR-ing. • AMS1117-3.3 voltage regulator to deliver a stable 3.3V supply to the microcontroller. • Filter capacitors (10μF electrolytic and 100nF ceramic) at the input and output of the regulators. • Protection features including USBLC6-2SC6 for USB ESD protection and TVS diodes for barrel jack overvoltage protection. Motor Control: • Incorporates an Omron G5LE relay with a PC817 optocoupler and BC547 transistor driver. • Provides dedicated header pins for servo motors with PWM outputs. • Flyback diode protection implemented for relay safety. I/O Connections: • Header pins exposing ESP32-C3 GPIOs: Digital I/O (IO0-IO10, IO18, IO19) and serial communication lines (TXD0, RXD0), plus an enable pin. • Each I/O pin includes appropriate 10kΩ pull-up/pull-down resistors to ensure reliable performance. Status Indicators: • A power status LED with a current-limiting resistor. • A user-controllable LED connected to one of the GPIO pins. PCB Layout Requirements: • 2-layer PCB design with separate ground planes for digital and power sections. • Placement of decoupling capacitors close to power pins to reduce noise. • Adequate trace width for power lines to ensure efficient current flow. • Inclusion of mounting holes at the board corners for secure installation. • All components are properly labeled with correct values for resistors, capacitors, and other passive elements, following standard design practices for noise reduction, stability, and reliability. #RoboticArmController #ESP32C3 #SchematicDesign #PCBDesign #ElectronicsDesign #PowerManagement #MotorControl #EmbeddedSystems #IoT
