ESP-12E WiFi Module

Wi-Fi Modem circuit can be turned off and CPU suspended to save power according to the 802.11 standard (U-APSD). E.g. in DTIM3, to maintain a sleep 300ms-wake 3ms cycle to receive AP’s Beacon packages, the current is about 0.9mA. Deep-Sleep does not require Wi-Fi connection to be maintained. For application with long time lags between data

Raspberry Pi Pico Datasheet - Components101

Power Supply (SMPS) power control and sensing the system voltages. Pico has been designed to use either soldered 0.1" pin-headers (it is one 0.1" pitch wider than a standard 40-pin DIP package) or can be used as a surface mountable 'module', as the user IO pins are also castellated. There are SMT pads

L298N Motor Driver Datasheet - Components101

Controlling Stepper Motor . In this example we have a typical . NEMA-17 stepper motor with four wires: The key to successful stepper motor control is identifying the wires - that is which one is which. You will need to determine the A+, A -, B+ and B - wires. With our example motor these are red, green, yellow and blue. Now let's get the wiring ...

The Double Bazooka Antenna

This is definitely not the antenna for the ham 2 It is of course possible to use a balun at the antenna if the direct coupling to the outside of the feed line causes " antenna " currents to flow on the line. With most random lengths of line these currents should be fairly small in a 3.5-Mc. system. — Editor. 1.5 3.5 3.7 3.8 FREQUENCY-MC. 4.0

Connecting Your Receiver to the Antenna - DXing.com

Not very elegant, and certainly not recommended, but it works. A more elegant solution is to use a BALUN transformer, with either 1:1 or 4:1 impedance transformation (depending on the line type). 6 Connecting to Coaxial Inputs Most high-end an d middle market receivers today are equipped with coaxial
