The boxes â supply segment groups â can be compared based on a weighted average Brent break-even price to define their relative competitiveness. Rystad Energy estimates that oil sands and the Arctic are the most expensive supply segments with an average breakeven of ~80 USD/bbl. Within offshore, shelf has the lowest average break-even price at ~60 USD/bbl, only marginally higher than Onshore Row.â.
The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
Arduino and Arduino-compatible boards use printed circuit expansion boards called shields, which plug into the normally supplied Arduino pin headers. Shields can provide motor controls, GPS, Ethernet, LCD, or breadboarding (prototyping). A number of shields can also be made DIY.n official Arduino Uno with descriptions of the I/O locations.
