Hello everyone! How are you this fine Friday? This week we are happy to announce that the kid tested, mother approved SparkFun Pulsed Radar Breakout is once again available! We fixed a couple issues we had with the board and secured a great supplier for the A111 chip. Following that, we have a new Big Easy Driver kit that should help you get started with stepper motors, an RTK Surveying Kit, and two U.FL cables (one to SMA, the other to RP-SMA). Don't forget, we still have a few SkeleBoards available for order. We won't be restocking those after they're gone, so get them before while you can! On to the new products!

It's baaaack!

SparkFun Pulsed Radar Breakout - A111

SparkFun Pulsed Radar Breakout - A111


Does your project require high precision, cutting-edge distance measurement? Or maybe speed, motion, or gesture sensing? We're not talking about simple ultrasonic or even infrared here, but 60GHz radar! Well say hello to the SparkFun A111 Pulsed Radar Breakout! The A111 is a single-chip solution for pulsed coherent radar (PCR) and comes complete with an integrated antenna and an SPI interface capable of clock speeds of up to 50 MHz. Though the A111's primary use case is distance sensing, it also supports applications in gesture, motion, material, and speed detection at distances of up to two meters.

SparkFun Big Easy Driver Kit


Do you have ideas for a project that moves, like a robot, automatic dog door or moving platform? Whatever the project, the SparkFun Big Easy Driver Kit is designed to help make it a reality. Included in this kit is our popular Big Easy stepper motor driver, a RedBoard, power supply, USB cable, and all other needed hook-ups. The only thing users will need to supply is their own motor.

SparkFun RTK Surveying Kit

SparkFun RTK Surveying Kit


The SparkFun RTK Surveying Kit has everything you need to get centimeter level global positioning measurements using GNSS RTK. We've created a handy carrying case to protect the most expensive parts, allowing you to quickly attach the L1/L2 antenna and RTK Surveyor housing to the pole or tripod of your choice. The kit includes all the antenna bits, cables and chargers you need to jump right into the field.

SparkFun Thing Plus SkeleBoard - ESP32 WROOM (U.FL)


As a reminder, we still have some SkeleBoards still available, but stock is running short. We've already sent out about half of what we had available since last week. The SparkFun Thing Plus SkeleBoard features a matte black PCB with a super scary skeleton design in white silk and one of our favorite references out of the last few years: (DOOT). We've also made sure to include a 2.4GHz U.FL PCB Antenna so you won't need to worry about picking up any additional parts to get your board up and running! Other than that, this board is identical to our existing SparkFun Thing Plus - ESP32 WROOM (U.FL).

Rules & Information:

  • Add the SparkFun Thing Plus SkeleBoard - ESP32 WROOM (U.FL) to your cart!
  • Use code "SKELEBOARD21" during checkout when your cart reaches $100 or more (not including this board or shipping/tax/discounts)
  • There is an order limit of five max per customer.
  • No rainchecks or backorders will be allowed. We will not be allowing the combining of orders during this sale. Distributor and Reseller accounts will not be eligible.

Don't worry, you can also purchase this product on its own, even without the promo code!

RP-SMA to U.FL Cable - 150mm

RP-SMA to U.FL Cable - 150mm


This SMA (or RP-SMA) to U.FL Cable is commonly used to attach WiFi, Bluetooth, or nRFxxx based devices to a 2.4 GHz antenna. What makes this unassuming cable special is the slightly longer length of 150 mm (compared to 100 mm). We found that the extra 50 mm makes all the difference when working with an enclosure.

That's it for this week! As always, we can't wait to see what you make! Shoot us a tweet @sparkfun, or let us know on Instagram or Facebook. We’d love to see what projects you’ve made! Please be safe out there, be kind to one another, and we'll see you next week with even more new products!

Never miss a new product!
