We've written hundreds of libraries and made lots of mistakes. Learn the basics of how to write a good library.
The costs and time required to get the world's first open source BLE module certified with the FCC.
Any FCC certified module needs a tin can to protect and prevent RF emissions. Check out how we did it for Artemis!
Checkout how we drilled through the back of a PCB in order to solder to the hidden pads under a cellular module.
Learn how we created our own SMD module using PCB tips and tricks for blind and buried vias.
SparkFun is pleased to announce a new line of development tools to help implement edge computing, including voice and image recognition.
If we've learned one thing at SparkFun it's that geeks love to talk about their projects! We can't wait to share what we've been cooking. Check out the pile of new products, sensors and breakout boards!
It's not pretty but we've come up with a way to make I2C based libraries even more flexible. Now you can pass a software I2C port into a library!
We've got the magnetic tile back in stock and the first boards made with Buzzard are in!
Watch out, we’ve been translating technical English… How to install and edit the SparkFun English file for the Charm High software.
To celebrate our "crystal anniversary," here's a collection of the stories, blog posts, products and adventures from 15 years of making crazy things.
Wherein I felt the urge to respond to a recent WIRED article that hits close to home.
What's in the box?! Opening a safe with a little intelligence and a little brute force.
We use 0603 SMD packages but the electronics world uses much smaller sized components.
When writing a library, pass in I2C ports to make the library more useful on different platforms.
Looking for information in the noise: a contest to crowdsource a better algorithm for accelerometer data.
I recommend the BlueSMiRF v2 for moving RTCM from a phone to the mosaic. While there isn't a direct plug-in connection, only 4 wires are needed (3.3V/GND/TX/RX). Any UART on the mosaic will work. If it were me, I would use COM4 simply because it doesn't have, nor do you need, flow control.
The RTK mosaic is a very good rover. The antenna is waterproof and can be mounted to the top of whatever platform you're using.
We have other products based on the mosaic-X5 but I can say what shape it will have since it's very early days.
They are very different beasts. The mosaic can receive on more bands (as member 1880499 points out), as well as greater anti-jamming detection, higher accuracy, built in web configuration, multi-NTRIP client/server for fall back, and many more features. The Reference Station is very good but the industry tends to view the mosaic as the 'gold standard' for base station and rover operation.
Excellent! Glad to hear it!
Facet with mosaic - yes, it's on our roadmap but there's a pile of very large barriers to make it work. Stay tuned!
what is the difference between the 915 MHz, 500 mW telemetry radio and the 915 MHz, 100 mW radio.
A higher power radio will theoretically get you longer range if there is line of sight.
Telemetry radios have to connect to the RTK Facet via USB or just the JST-GHR-04V to JST-GHR-06V Cable
An external radio cannot be connected over USB. It needs to be attached to the 4-pin RADIO connector using the included 4-pin JST connector or the included 4-pin to 6-pin cable (which can directly connect to the LoRaSerial or [HolyBro](https://www.sparkfun.com/products/19032 radios).
What benefit does the SparkFun LoRaSerial Kit have to the telemetry radio?
LoRaSerial is a 1W radio utilizing the LoRa modulation technique for long range applications.
Thanks! Glad you liked it.
That page is generated by the mosaic not the ESP32. The ESP32 is just forwarding the packets (aka the HTML you see) from the mosaic to WiFi.
A fine idea! It was not on our roadmap but I'll add it.
Thank you for the kind words! Happy to hear it is working well.
Yes, an external power bank works great. Plug the power bank into the CONFIG UBLOX connector for the most efficient charging.
A larger antenna mounted as high as possible is your best bet. We offer these antennas that work well but are large.
How can I connect these antennas to the RTK Facet using what cable
The cable included with the RTK Facet is designed to directly plug and play with these radios (or the telemetry radios).
what distance can be obtained
Depends on your surroundings. These will not transmit through hills or large natural objects (aka rocks). Buildings, etc degrade the distance. In general open air, you can get a few miles. In an urban setting, it's a few blocks.
what is the difference between serial lora and the teletry radio
The LoRaSerial is built for maximum range, where as the telemetry radios are optimized for greater data bandwidth.
