ESP8266 D1 Mini Products

Description

The ESP8266 D1 Mini is a low power WiFi development board with a small form factor of 34.2mm x 25.6mm (1.35in x 1.01in). It was first created by Wemos, a Chinese company that designs IoTInternet Of Things products, and several clones of the board followed.

The ESP8266 Wemos D1 Mini has been through several revisions, with V4.0.0 as the current version of the board (documentation can be found at wemos.cc).

The ESP8266 Wemos D1 Mini V4.0.0 contains the following components:

• ESP8266EX SoCSystem On a Chip (Datasheet PDF)
• 4MB flash memory chip
• 40MHz Crystal Oscillator
• PCBPrinted Circuit Board antenna
• 4-Pin JST-SH I2CInter-Integrated Circuit. Also referred to as IIC or I²C. connector
• USB Type-C connector for power and data transfer
• CH340 USB-to-TTL converter chip
• 3.3V LDOLow Dropout Regulator voltage regulator
• Reset button on the side of the board
• 1x blue LEDLight Emitting Diode connected to GPIO2
• 16x pin through holes (8-Pins on each side of the board) with 0.1" (2.54mm) spacing

The I/O pins on the D1 Mini are 3.3V (max) and include:

• 11x GPIOGeneral Purpose Input Output with PWMPulse-Width Modulation
• 1x analog input (10-bit ADCAnalog-to-Digital Converter (ADC, A/D, or A-to-D), 3.2V max input)
• 1x UARTUniversal Asynchronous Receiver-Transmitter, 1x I2CInter-Integrated Circuit. Also referred to as IIC or I²C., and 1x SPISerial Peripheral Interface

There is also a 4-Pin JST-SH connector for I2C on the top of the board. However, the VCCVoltage Collector Collector (VCC) is the supply voltage at the collector of a transistor. The double subscript notation of repeating letters "CC" is used to denote a power supply voltage that is relative to ground. and GNDCommon Ground pins on this connector are not compatible with the SparkFun's QwiicQwiic connectors are SparkFun's name for 4-pin JST SH connectors with 1.0mm pitch. These connectors were implemented on SparkFun boards to make it easy to plug-n-play various sensors and devices without soldering and wiring. Qwiic is cross-compatible with Adafruit's STEMMA QT connectors. and Adafruit's STEMMA QTSTEMMA QT ('cutie') connectors are Adafruit's name for 4-pin JST SH connectors with 1.0mm pitch. These connectors were implemented on Adafruit boards to make it easy to plug-n-play various sensors and devices without soldering and wiring. The STEMMA QT (JST SH) are a smaller connector than the STEMMA (JST PH) that do not fit on smaller boards. STEMMA QT is cross-compatible with SparkFun Qwiic connectors. connectors: instead of Qwiic/STEMMA QT pinout of GND-VCC-SDA-SCL, the D1 Mini board is using GND-SDA-SCL-VCC.

Another version of the ESP8266 D1 Mini board uses the ESP-12F module. This version of the board has RF shielding and comes with either a Micro-B or Type-C USB connector; otherwise it has the same size and pin compatibility as the Wemos board.

One benefit of the D1 Mini is the variety of shields available for the board. The LiPoLithium Polymer/Li-ionLithium-ion Battery Shield is provided in the accessories section on this page. A more comprehensive list of shields can be found at wemos.cc.
