The Arduino Pro Mini is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. A six pin header can be connected to an FTDI cable or Sparkfun breakout board to provide USB power and communication to the board. The Arduino Pro Mini is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with the Arduino Mini. The Arduino Pro Mini was designed and is manufactured by SparkFun Electronics.

The RedBoard Artemis has the improved power conditioning and USB to serial that we've refined over the years on our RedBoard line of products. A modern USB-C connector makes programming easy. A Qwiic connector makes I²C easy. The RedBoard Artemis is fully compatible with SparkFun's Arduino core and can be programmed easily under the Arduino IDE. We've exposed the JTAG connector for more advanced users who prefer to use professional tools' power and speed. We've added a digital MEMS microphone for folks wanting to experiment with always-on voice commands with TensorFlow and machine learning. We've even added a convenient jumper to measure current consumption for low power testing. With 1MB flash and 384k RAM, you'll have plenty of room for your sketches. The on-board Artemis module runs at 48MHz with a 96MHz turbo mode available and with Bluetooth to boot! Features Arduino Uno R3 Footprint 1M Flash / 384k RAM 48MHz / 96MHz turbo available 24 GPIO - all interrupt capable 21 PWM channels Built-in BLE radio 10 ADC channels with 14-bit precision 2 UARTs 6 I²C buses 4 SPI buses PDM Interface I²S Interface Qwiic Connector

Included on every OpenLog Artemis is an IMU for built-in logging of triple-axis accelerometer, gyro, and magnetometer. The OpenLog Artemis uses the latest ICM-20948 from InvenSense capable of nearly 250Hz logging of all nine axes. Simply power up the OpenLog Artemis and all incoming serial data is automatically recorded to a log file with baud rates up to 500000bps, supported! The OLA also has four ADC channels available on the edge of the board. Voltages up to 2 V can be logged with 14-bit precision up to 1900 Hz for one channel and 1000Hz logging all four channels. Additionally, based on feedback from users we've added an on-board RTC so that all data can be time stamped. The OpenLog Artemis is highly configurable over an easy to use the serial interface. Simply plug in a USB-C cable and open a terminal at 115200 bps. The logging output is automatically streamed to both the terminal and the microSD. Pressing any key will open the configuration menu. The OpenLog Artemis automatically scans, detects, configures, and logs various Qwiic sensors plugged into the board (No soldering! No programming!). This OpenLog uses common microSD cards to record clear text, comma-separated files. You probably already have a microSD card laying around but if you need any additional units to see the related items below. The OpenLog Artemis supports microSD cards formatted as FAT32 as well as the older FAT16 formats up to 32GB. Currently, the OpenLog Artemis does not support microSD cards formatted with exFAT. Very low power logging is supported. OpenLog Artemis can be configured to take readings at 500 times a second, or as slow as 1 reading every 24 hours. You choose! When there is more than 2 seconds between readings OLA will automatically power down itself and the sensors on the bus resulting in a sleep current of approximately 18uA. This means a normal 2Ah battery will enable logging for more than 4,000 days! OpenLog Artemis has built-in LiPo charging set at 450 mA/hr. New features are constantly being added so SparkFun has released an easy to use firmware upgrade tool. No need to install Arduino or a bunch of libraries, simply open the Artemis Firmware Upload GUI, load the latest OLA firmware, and add features to OpenLog Artemis as they come out! Features Artemis Module (Cortex-M4F based Apollo3 microcontroller) Configurable via CH340E and Artemis Firmware Upload GUI Operating voltage range 3.3 V to 6.5 V (via VIN with optional external power switch) 5 V with USB (via 5 V or USB type C) 3.6 V to 4.2 V with LiPo battery (via VBATT or 2-pin JST) Built-in MCP73831 single cell LiPo charger Minimum 450mA charge rate 3.3 V (via 3V3) Current consumption ~20 mA (Run) ~80 µA (Sleep) ~18 µA (Deep Sleep - regulator shut down) Ports 1 x USB type C 1 x LiPo battery enabled 1 x Qwiic enabled I²C with power control 1 x SWD 2x5 header 4 x Analog-to-digital 14-bit, up to 1900 Hz, 2 V max (3.3 V compatible) Serial Logging speeds up to 500000bps 1 x microSD socket Support for FAT32 and older FAT16 formats up to 32GB with power control RTC with 1mAhr battery backup 9-axis IMU logging up to 250 Hz ICM-20948 via SPI interface LEDs Power LiPo charge indicator Serial Tx and Rx Status

This tiny little board does all of the neat Arduino tricks that you're familiar with: nine channels of 10-bit ADC, five PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 5 V and 16 MHz, this board will remind you a lot of your other favourite Arduino-compatible boards, but this little guy can go just about anywhere. There is a voltage regulator on board so it can accept voltage up to 6 VDC. If you're supplying unregulated power to the board, be sure to connect to the 'RAW' pin on not VCC. The reset button's benefit is to quickly reset the board or place it into bootloader mode without the need to take out a piece of the jumper wire. The USB micro-b connector has been replaced with the USB type C connector. The through-hole pads have castellated edges for each pin to add a lower profile in your projects should you decide to build it into another assembly during production.

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 mm 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.
