Nano Microcontroller
The cheapest microcontroller that has the least amount of memory and pins. Great for simple projects that don't require a lot of resources.
How to Acquire
Currently, there is no crafting recipe for the Nano, and it is not accesible in the creative inventory. It can be spawned in using the /give command.

Specs
| Spec | Value | Unit | Usage |
|---|---|---|---|
| CPU | mos6502 | ||
| Clock Speed | 800 | Hz | |
| ROM | 8096 | Bytes | Program Code, Vectors, LUTs |
| RAM | 512 | Bytes | 256B ZeroPage, 256B Stack Memory |
| Pins | 4 |
Pinout
Pins are numbered from 0 to 3, and they ordered in a clockwise fashion starting from the top and ending at the left. Note that the top right yellow corner of the block indicates the orientation of the pins. They are also labeled in order: front, right, back, and left.
Address Map
The Nano has a 64KB address space, with 8KB of ROM and 512 bytes of RAM.
| Address Range | Name | Uses |
|---|---|---|
0x0000 - 0x0200 | RAM | 256 bytes zero page memory | 256 byte stack |
0x7000 - 0x7070 | GPIO | Pin Control/Interrupts |
0x7100 - 0x7110 | EL | Minecraft Event Listener |
0x7200 - 0x7208 | UART | Serial Communication |
0xE000 - 0x10000 | ROM | Program Code, Vectors, LUTs |
Modules
-
GPIO - Control and read the state of the pins of a microcontroller via the processor's data bus. It has a buffer of
64bytes to store the state of every pin, but only the first four are used by the pin drivers. -
EL - Provides a simple way to listen for Minecraft events to execute code in response.
-
UART - Serial communication module that allows the microcontroller to send and receive data to and from other devices.
