The HERO Board is the programmable brain in 30 Days Lost in Space and Cogsworth City. You write C++, upload it over USB, and the board runs it: blinking lights, reading buttons and sensors, driving screens and buzzers.
A second board means a finished project can stay wired up on your desk while you start the next one. It's the same board the lessons, the browser simulator, the HERO Shields Pack and the 37-in-1 Sensor Kit walkthroughs are built around.

“Good value. Does what it says on the tin. I'm building this one into a solar powered weather station with barometric pressure, temperature and light intensity sensors. I will be adding an ESP32 WiFi comms processor so I don't need to open the box to download the data.” — Trevor C.
“I needed a new Hero board for ongoing projects.” — Mark S.
“Works great!” — Max
“Love these products!” — Vincent D.
Yes. It's the HERO Board from 30 Days Lost in Space and Cogsworth City, so the lessons and circuits made for those kits run on it.
In C++. On a Windows, Mac or Chromebook computer with Chrome or Edge, the Upload To Board button on a lesson page or in the sandbox sends your code to the board over the USB cable. It also works with the desktop IDE.
Yes. The browser simulator at craftingtable.com runs a virtual HERO Board, chip and all, so you can wire and run a circuit on screen first. It needs a laptop or desktop computer.
Yes. The schematics, board images and editable design file are published under CC BY-SA 3.0 at github.com/inventrkits/HERO.
No. It's the board and the USB cable. If you want parts and lessons too, 30 Days Lost in Space includes a HERO Board along with the parts its missions use.
