NodeMCU is a low-cost open source IoT platform. [ 4 ] [ 5 ] It initially included firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which was based on the ESP-12 module.
SparkFun ESP8266 Thing. The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred to as ...
ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...
In December 2012, Allwinner announced the availability of two ARM Cortex-A7 MPCore powered products, the dual-core Allwinner A20 and quad-core Allwinner A31. Production of the A31 started in September 2012 and end products, mostly high-end tablets from Chinese manufacturers, appeared on the market in early 2013, including the Onda V972.
Figure 1. General structure of the loline alkaloids produced in grasses infected by fungi of the Epichloë/Neotyphodium complex (epichloae endophytes); R' and R'' denote variable substituents that can include methyl, formyl, and acetyl groups giving rise to different loline species.
Preserved City of Oxford Motor Services Loline II. The Dennis Loline was basically a license-built Bristol Lodekka, being primarily supplied to municipal, private sector British Electric Traction fleets and independent bus companies in the United Kingdom, during a period when Bristol's sales were restricted to state-owned bus companies.
Neoverse V3 (code named Poseidon) was teased by Arm alongside the V2 and E2 announcements. [15] It is targeted for systems including DDR5 , PCIe gen6 , and CXL 3.0 . The codename Poseidon was first used for the generation succeeding Zeus , now V1, and targeted for 2021 on a 5nm node.
The Arduino Nano is an open-source breadboard-friendly microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2008.
