Product Description
LARSON SCANNER 2021
What is it?
Larson Scanner 2021 is the 4th revision of this popular product. And this version has way more features.
Why did you make it?
It's fun! Need any more reasons? And this new version is also more practical.
What makes it special?
Instead of using an ATtiny13 or similar this time I am using an ATtiny3216 and 16 addressable RGB LEDs. Besides the Larson Scanner pattern, one can program it with different patterns and there is a push button to select different function/patterns. There is more to it though. Onboard the PCB, which is same size as previous versions (165x17mm), there is also an I2C ambient light and temperature sensor, and a microphone! On the back you can solder Grove-style connectors giving access to UART, I2C & GPIO including DAC output. Supplied are right angle PH2.54 connectors but the connections are more or less following Grove ecosystem guidelines It is powered through the mUSB connector but can also use PSU4056L modules same as previous versions. mUSB is also used to access the UPDI programming pin and I even made a programmer to help with this (optional) Larson Scanner is using WS2812C addressable RGB LED for relatively low power consumption.
Using the LED array as a bar graph you can program it as a VU Meter, Thermometer, Night Light, or an indicator for various conditions limited only by your imagination. An add-on board is also in progress which will hold a 14500 Li-Ion or LiFePO4 cell and power management (charger etc.) and possibly a small audio amplifier & speaker to use with the DAC output.
- How many LEDs? 16x WS2812C RGB addressable LEDs
- How much current? around 5mA when idle with LED off, 250mA max
- What kind of power supply is needed? Any micro USB 5VDC source will be just fine but any 5VDC source can also be used. Combined with the PSU4056 voltage regulator, it can be used in an automotive environment or be powered from any DC source from 5-40VDC. Below you can add a modified PSU4056 using ceramic capacitors only for a slim profile.
I have also made a simple programmer for the new Larson Scanner as the UPDI is passing through the mUSB port.
- Ambient light sensor OPT3001
- Temperature Sensor LM75BDP,118
- Microphone AP2718AT
LARSON SCANNER 2021 is using ATtiny3216
Why GroupGets?
Ordering more PCBs and components in volume helps maintain low cost but also helps fund me to design and prototype more interesting projects.

Options and Add-Ons
UPDI programmer adapter
$3.00
This is a small adapter to allow programming using Arduino IDE.
UPDI programming pin is accessible via the mUSB connector.
Arduino Nano NOT included.
PSU4056
$3.00
PSU4056 is a small buck converter which allows powering Larson Scanner with a higher voltage (28V max)
Photo shows big electrolytic capacitors but in the version for Larson Scanner will be replaced by ceramic capacitors so the board will be as low-profile as possible.

BurgduinoIt took long enough to get to make the first LS2021 but they are here and they are much more impressive than camera can picture them!
I set the goal of the campaign to 50pcs, but i really hope demand will ask for more...
IF more than 100pcs are backed, i will supply a FREE buck converter to each backer... if more than 200pcs, will provide a FREE programming adapter.. and if more than 300 then all backers will receive a FREE bundle of buck converter & programmer adapter... IF THEY ALREADY purchased one or more of each with their backing, I will decide depending on total pcs ordered and total pcs backed in the campaign what i can add to their orders to thank all of them!
Approved ✓
We are proud to support Larson Scanner 2021 in reaching its goal. Once the target has been reached the product will be distributed to all backers. Don't miss out on becoming a backer!
