It accepts I2C or PWM signals and converts them for applications such as 0-5V, 0-10V and 4-20mA control.It is designed for automation and control projects using boards such as Arduino, ESP32, Raspberry Pi and STM32. Typical uses include variable frequency drive speed control, 0-10V LED dimming, proportional valves, water pumps, lab signal generation and retrofitting older analogue equipment.The module supports 8 adjustable I2C addresses, so up to 8 devices can be cascaded for multi-channel projects from a single controller interface. It uses the DFRobot Gravity PH2.0 interface and includes both a Gravity-4Pin I2C/UART sensor cable and a Gravity-3Pin analogue sensor cable.Features:Signal conversion: Converts I2C or PWM input signals into stable 0-5V, 0-10V, or 4-20mA outputsHigh resolution: 16-bit resolution in I2C modeIndustrial output support: Suitable for 0-10V voltage control and 4-20mA current loop applicationsScalable addressing: Supports cascading up to 8 devicesAdjustable I2C addresses: 8 adjustable I2C addressesController compatibility: Works with logic-level controllers like Arduino, ESP32, Raspberry Pi and STM32Gravity connection: Uses the standard Gravity PH2.0 interfaceIncluded cables: Gravity-4Pin I2C/UART Sensor Cable ×1Included cables: Gravity-3Pin Analog Sensor Cable ×1Specifications:Chip Model: GP8600Operating Voltage: 3.3V-5VPower/Communication Interface: PH2.0-4Pin/3PinInput Signal: I2C / PWMCurrent Output Range: 0-20mAVoltage Output Range: 0-6V / 0-12VNumber of Channels: 1 channelResolution: 16-bit (I2C mode)Resolution: 8-bit, 10-bit (PWM mode, selectable based on controller)Full-Scale Error: ±0.2% (measured after fitting calibration)Value Range (I2C Mode): 0-65535 corresponds to 0-6V, 0-12V, or 0-20mAValue Range (PWM Mode): 0-255 corresponds to 0-6V, 0-12V, or 0-20mA, 0-1023 corresponds to 0-6V, 0-12V, or 0-20mAPCB Dimensions: 38 × 32 × 12.39 mmMounting Hole Spacing: 25mmMounting Hole Diameter: 3.0 mmA product wiki is available from DFRobot for setup information and project guidance. **Product Type:** DAC Module ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDTboCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--1f65c10fd9cdab4437d6fd2cfdea021eb35bc140/DFR1229_Main_01.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDUroCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--1872f1f808dc7b6bc7978368e0c20e1347de4369/DFR1229_Dim_02.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDV7oCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--f4f59e359512d9273a554fae85267a0f75c87585/DFR1229_Back_03.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDX7oCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--46bd07197ea1f0887ab0a6b922e1912a2e7a6745/DFR1229_Detail_04.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDZroCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--b47853793df950efc9f0150bce1c1247417d58a2/DFR1229_ShipList_06.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
