The CH34X family comprises widely used USB‑to‑serial chips manufactured by WCH (WinChipHead), commonly integrated into generic UNO R3, ESP8266, and ESP32 development boards.
Overview
- ✅ 【TRUE 16-BIT PRECISION WITH PROGRAMMABLE GAIN】Texas Instruments ADS1115 delivers 16-bit resolution across 4 single-ended or 2 differential analog channels. Six software-selectable PGA input ranges from ±0.256V to ±6.144V resolve voltage changes down to 7.8 microvolts per LSB — suitable for thermocouples, strain gauges, pH probes, and load cells.
- ✅ 【GOLD EDITION FINISH (ENIG, LEAD-FREE)】Each module features ENIG (Electroless Nickel Immersion Gold) plating for good solderability and oxidation resistance. Lead-free RoHS-compliant construction.
- ✅ 【I2C INTERFACE — CHAIN UP TO 4 MODULES (16 CHANNELS)】Standard I2C communication uses 2 wires (SDA/SCL) plus power and ground. Four selectable addresses (0x48–0x4B) via the ADDR pin allow up to 4 ADS1115 modules on the same bus for up to 16 analog channels — suitable for multi-sensor data loggers and monitoring projects.
- ✅ 【3.3V & 5V COMPATIBILITY】Operates on 2.0V to 5.5V supply with logic tolerant of bo... Read More...
