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.
In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI / IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations .

Periodic table (crystal structure) For elements that are solid at standard temperature and pressure the first table gives the crystalline structure of the most thermodynamically stable form (s) in those conditions. Each element is shaded by a color representing its respective Bravais lattice, except that all orthorhombic lattices are grouped ...
