Four 16-bit analog inputs with programmable gain
The ET-S08 is built around the TI ADS1115 — 16-bit ΔΣ, 4 single-ended / 2 differential, PGA ±0.256 to ±6.144V, 8–860 SPS, comparator. It connects over I²C 0x48 default / 0x49 / 0x4A / 0x4B (JP3) and is powered from VIN 2.0–5.5V; analog inputs 0…VIN.
Two Qwiic / STEMMA QT connectors let you chain it with other boards without soldering, and the 2.54 mm header fits a breadboard.
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Reading analog sensors precisely
- Battery voltage monitoring
- Adding ADC inputs to a Raspberry Pi
