Waveshare 3.5inch Resistive Touch Display (B) for Raspberry Pi 480×320 IPS Screen SPI Waveshare Modbus RTU 8-channel Relay Module RS485 Energy Efficient - Minimal power

Energy Efficient - Minimal power draw

Utilize the dual-core architecture by assigning sensor data collection to one core while the other handles Wi-Fi communication

and the module integrates a complete transceiver with built-in frequency synthesizer

but UV exposure can gradually degrade the epoxy resin matrix over time

Each resistor undergoes rigorous quality control testing to verify resistance value
