SparkFun OpenLog by SparkFun Electronics

Autodesk EAGLE Design Block Description: The SparkFun OpenLog is an open source data logger that works over a simple serial connection and supports microSD cards up to 64GB. The OpenLog can store or “log” huge amounts of serial data and act as a black box of sorts to store all the serial data that your project generates, for scientific or debugging purposes. The SparkFun OpenLog runs off of an onboard ATmega328, running at 16MHz thanks to the onboard crystal.The OpenLog draws 6mA when recording a 512 byte buffer, but as that process takes a fraction of a second, the average current draw is closer to 5mA. Keep in mind though that if you are recording a constant data stream at 115200bps, you will approach that 6mA limit. All data logged by the OpenLog is stored on the microSD card that involves the features of 64MB to 64GB capacity and FAT16 or FAT32 file type. Features: VCC Input: 3.3V-12V (Recommended 3.3V-5V) Log to low-cost microSD FAT16/32 cards up to 64GB Simple command interface Configurable baud rates (up to 115200bps) Preprogrammed ATmega328 and bootloader Four SPI pogo pins Two LEDs indicate writing status 2mA idle, 6mA at maximum recording rate

SparkFun nRF52832 Breakout by SparkFun Electronics

Autodesk EAGLE Design Block Description: The nRF52832 is Nordic Semiconductor’s latest multiprotocol radio System on Chip (SoC). It’s half microcontroller, with a list of features including 32 configurable I/O pins, SPI, I2C, UART, PWM, ADC’s, 512kB flash, and 64kB RAM. And it’s half 2.4GHz multiprotocol radio, supporting Bluetooth Low Energy (BLE), ANT, and Nordic’s proprietary 2.4GHz ultra low-power wireless communication – it even features on-chip NFC tag support. SparkFun’s nRF52832 Breakout provides easy access to all of the chip’s features. It breaks out all of the nRF52’s I/O pins, provides a 32.768kHz RTC crystal, a user-programmable button and LED, and a trace antenna to send and receive those 2.4GHz transmissions. Plus, to make the chip as easy-to-flash as possible, the breakout comes pre-programmed with a serial bootloader. Nordic’s nRF52832 is a SoC that combines an ARM Cortex-M4F microprocessor with a 2.4GHz multiprotocol radio. In addition to providing access to all of the chip’s I/O pins, the breakout board includes a handful of external components. The nRF52832 can operate on a power supply between 1.7 and 3.6V. The board also includes a 3.3V regulator with a maximum input of 6V, if you want to power the board with batteries or a regulated wall supply. Features: Bluetooth Low Energy (BLE), ANT and proprietary 2.4GHz radio support 32-bit ARM Cortex-M4F Processor Easy access to all 32 GPIO SPI, I2C, UART, PWM and ADC I/O support User-programmable LED and button 32.768kHz RTC Crystal Pre-programmed serial bootloader

SparkFun XBee Explorer USB by SparkFun Electronics

Autodesk EAGLE Design Block Description: This is a simple to use, USB to serial base unit for the Digi XBee line. This unit works with all XBee modules including the Series 1 and Series 2.5, standard and Pro version. Plug the unit into the XBee Explorer, attach a mini USB cable, and you will have direct access to the serial and programming pins on the XBee unit. The highlight of this board is an FT231X USB-to-Serial converter. That’s what translates data between your computer and the XBee. There’s also a reset button, and a voltage regulator to supply the XBee with plenty of power. In addition, there are four LEDs that’ll help if you ever need to debug your XBee: RX, TX, RSSI (signal-strength indicator), and power indicator. This board also breaks out each of the XBee’s I/O pins to a pair of breadboard-compatible headers. So if you want to make use of the XBee’s extended functionality, you can solder some header pins into those, or even just solder some wire.

SparkFun LiPo Charger Basic - Micro-USB by SparkFun Electronics

Autodesk EAGLE Design Block Description: If you need to charge LiPo batteries, this simple charger will do just that, and do it fast! The SparkFun LiPo Charger Basic is stripped down of all features and just does one thing well - charge 3.7V LiPo cells at a rate of 500mA. It is designed to charge single-cell Li-Ion or Li-Polymer batteries. Check the datasheet below to see if it will work with your battery. The board incorporates a charging circuit, status LED, connector for your battery (JST-type used in the batteries we carry), and a micro-USB connector. A small mounting hole allows this charger to be easily embedded into a project. Note: This version uses a micro-USB cable. We also have this charger with a mini-USB connection as well. Dimensions: 29.4x10.8mm
