NodeMCU was created shortly after the ESP8266 came out. On December 30, 2013, Espressif Systems [ 6 ] began production of the ESP8266. [ 12 ] NodeMCU started on 13 Oct 2014, when Hong committed the first file of nodemcu-firmware to GitHub. [ 13 ]
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 ...
A GPIO port is a group of GPIO pins (often 8 pins, but it may be less) arranged in a group and controlled as a group. GPIO abilities may include: [2] GPIO pins can be configured to be input or output; GPIO pins can be enabled/disabled; Input values are readable (usually high or low) Output values are writable/readable
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 ...
A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.
It appears Kendrick Lamar had more than one special guest during his Super Bowl 59 halftime show performance. A protestor was tackled on the field.
