The Uno board was the successor of the Duemilanove release and was the 9th version in a series of USB-based Arduino boards. [8] Version 1.0 of the Arduino IDE for the Arduino Uno board has now evolved to newer releases. [ 4 ]
Seeeduino V4.2 is an Arduino-compatible board, which is based on ATmega328P MCU, Arduino UNO bootloader, and with an ATmega16U2 as a UART-to-USB converter. The three on-board Grove interface can make your board connect to over 300 Grove modules. Seeeduino Cortex-M0+] SAMD21 Cortex-M0+ Seeed Studio

There are several types of timeline articles. Historical timelines show the significant historical events and developments for a specific topic, over the course of centuries or millennia. Graphical timelines provide a visual representation for the timespan of multiple events that have a particular duration, over the course of centuries or ...
Ramon Llull invented the Lullian Circle: a notional machine for calculating answers to philosophical questions (in this case, to do with Christianity) via logical combinatorics. This idea was taken up by Leibniz centuries later, and is thus one of the founding elements in computing and information science. c. 1416
The main improvements over the Manchester Mark 1 were in the size of the primary storage (using random access Williams tubes), secondary storage (using a magnetic drum), a faster multiplier, and additional instructions. The basic cycle time was 1.2 milliseconds, and a multiplication could be completed in about 2.16 milliseconds.
The clock of the Intel 8008 was set at 500 kHz, the memory was 16 kilobytes. A bus, called Pluribus was introduced and allowed connection of up to 14 boards. Different boards for digital I/O, analog I/O, memory, floppy disk were available from R2E.

Javelins, 400,000 years ago. (Homo sapiens sapiens – modern human anatomy arises, around 100,000 years ago.) Glue, 200,000 years ago.
