This Wi-Fi module is based on the popular ESP8266 chip. The module is FCC and CE certified and RoHS compliant.
Fully compatible with ESP-12E. 13 GPIO pins, 1 analog input, 4 MB flash memory.
The flexibility of the Artemis module starts with SparkFun's Arduino core. You can program and use the Artemis module just like you would an Uno or any other Arduino. The time to first blink is just 5 minutes away! We built the core from the ground up, making it fast and as lightweight as possible.
Next is the module itself. Measuring 10 x 15 mm, the Artemis module has all the support circuitry you need to use the fantastic Ambiq Apollo3 processor in your next project. We're proud to say the SparkFun Artemis module is the first open-source hardware module with the design files freely and easily available. We've carefully designed the module so that implementing Artemis into your design can be done with low-cost 2-layer PCBs and 8mil trace/space.
Made in the USA at SparkFun's Boulder production line, the Artemis module is designed for consumer-grade products. This truly differentiates the Artemis from its Arduino brethren. Ready to scale your product? The Artemis will grow with you beyond the Uno footprint and Arduino IDE. Additionally, the Artemis has an advanced HAL (hardware abstraction layer), allowing users to push the modern Cortex-M4F architecture to its limit.
The SparkFun Artemis Module is fully FCC/IC/CE certified and is available in full tape and reel quantities. With 1M flash and 384k RAM, you'll have plenty of room for your code. The Artemis module runs at 48MHz with a 96MHz turbo mode available and with Bluetooth to boot!

This FeatherWing will make it easy to add data logging to any Feather Board you might have. You get both an I²C real-time clock (PCF8523) with 32 KHz crystal and battery backup, and a microSD socket that connects to the SPI port pins (+ extra pin for CS).
Note: FeatherWing doesn't come with a microSD card.
A CR1220 coin cell is required to use the RTC battery-backup capabilities. If you're not using the RTC part of the FeatherWing, a battery is not required.
To talk to the microSD card socket Arduino's default SD library is recommended. Some light soldering is required to attach the headers onto the Wing.
Pinouts
Power pins
On the bottom row, the 3.3 V (second from left) and GND (fourth from left) pin are used to power the SD card and RTC (to take a load off the coin cell battery when main power is available)
RTC & I²C Pins
In the top right SDA (rightmost) and SCL (to the left of SDA) are used to talk to the RTC chip.
SCL - I²C clock pin to connect to your microcontroller's I2C clock line. This pin has a 10 kΩ pull-up resistor to 3.3 V
SDA - I²C data pin to connect to your microcontroller's I2C data line. This pin has a 10 kΩ pull-up resistor to 3.3 V
There's also a breakout for INT which is the output pin from the RTC. It can be used as an interrupt output or it could also be used to generate a square wave.
Note that this pin is an open drain - you must enable the internal pull-up on whatever digital pin it is connected to.
SD & SPI Pins
Starting from the left you've got
SPI Clock (SCK) - output from feather to wing
SPI Master Out Slave In (MOSI) - output from feather to wing
SPI Master In Slave Out (MISO) - input from wing to feather
These pins are in the same location on every Feather. They are used for communicating with the SD card. When the SD card is not inserted, these pins are completely free.
The Voice Interaction Satellite Kit can extend the reach of your base station to each room in your house and enable you to interact with the hardware based on where you issue your commands! You can arrange multiple Satellite Kits throughout your home to add new functionality to Base kit or any other smart speaker, extending your voice control across several rooms.
The Voice Interaction Satellite Kit is powered by a Raspberry Pi Zero W and the ReSpeaker 2-Mics Pi HAT. Along with the kit comes a speaker, a Grove - Temperature Humidity Sensor (SHT31) sensor, a Grove Relay, and a pegboard to hang it on a wall or create a nifty stand.
Note
All Satellite Kits require a Base kit or Raspberry Pi in order to operate as intended.
