If you're looking to level up your project, the Mega 2560 is a great place to start. It's based on the Atmega2560 chip which provides a huge number of IO pins and functionality.

A 433MHz antenna that utilizes an SMA connector and is 200mm long with a gain of 2dBi...

Never hunt around for another crystal again, with the Si5351A clock generator breakout from Adafruit! This chip has a precision 25MHz crystal reference and internal...

This simple spring antenna matches great with any of our 433MHz RFM and LoRa breakouts, bonnets and Feathers. They're made of copper-clad wire so you can solder...

Great for use with the DS1307.

Good stability and far more accurate than MCU internal oscillators.

The 915MHz SiK Telemetry Radio V3 is a lightweight and inexpensive open source radio platform that can allow for ranges of 300m or more out of the box...

Keep your microcontroller tickin' with a a fancy timing crystal. This 16.000 MHz model comes in a HC49/US 'short style' standard package and is breadboard friendly...

This is an evaluation board for the Silicon Laboratories Si4703 FM tuner chip. Beyond enabling you to tune in to FM radio stations, the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information. The Si4703 even does a very good job of filtering and carrier detection. It also enables data such as the station ID and song name to be displayed to the user.

These wireless receivers work with our 434MHz transmitters. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only receivers, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair.

Wireless switch with strong penetrability and easy expansion...

Standard ‘Watch’ or Real-Time-Clock crystal. 32.768kHz means it is precisely half of a 16-bit counter. Start counting at 0x8000 (or 32768). When the counter rolls over from 65535 to 0, then you know that exactly one second has passed. Reset the interrupt, reset the counter, and start counting again! Rated at 12.5pF load capacitance, 35K ohm max (18K ohm typical) series resistance, and +/- 20ppm stability. Small cylinder package.

This is the SparkFun RFM69 Breakout, a small piece of tech that breaks out all the pins available on the RFM69HCW module as well as making the transceiver easy to use. The RFM69HCW is an inexpensive and versatile radio module that operates in the unlicensed ISM (Industry, Science and Medicine) radio band. It’s perfect for building inexpensive short-range wireless networks of sensors and actuators for home automation, citizen science and more.
