The Elektor Super Servo Tester can control servos and measure servo signals. It can test up to four servo channels at the same time. The Super Servo Tester comes as a kit. All the parts required to assemble the Super Servo Tester are included in the kit. Assembling the kit requires basic soldering skills. The microcontroller is already programmed. The Super Servo Tester features two operating modes: Control/Manual and Measure/Inputs. In Control/Manual mode the Super Servo Tester generates control signals on its outputs for up to four servos or for the flight controller or ESC. The signals are controlled by the four potentiometers. In Measure/Inputs the Super Servo Tester measures the servo signals connected to its inputs. These signals may come from for instance an ESC, a flight controller, or the receiver or another device. The signals are also routed to the outputs to control the servos or the flight controller or ESC. The results are shown on the display.

The STM32 microprocessor with dual-core Cortex-M7 and Cortex-M4, together with onboard memory and audio jack enables you to perform machine learning and signal processing on the edge. Microcontroller (STM32H747XI) This dual core 32-bits microcontroller allows you have two brain talking to each other (a Cortex-M7 at 480 MHz and a Cortex-M4 at 240 MHz) you can even run micropython in one and Arduino in the other. Wireless communication (Murata 1DX) Whether you prefer Wi-Fi or Bluetooth, the Giga R1 WiFi got you covered. You can even quickly connect to the Arduino IoT Cloud and keep track of your project remotely. And if you are concerned about the security of the communication, the ATECC608A keeps everything under control. Hardware ports and communication Following the legacy of the Arduino Mega and the Arduino Due, the Giga R1 WiFi has 4x UARTs (hardware serial ports), 3x I²C ports (1 more than its predecessors), 2x SPI ports (1 more than its predecessors), 1x FDCAN. GPIOs and extra pins By keeping the same form factor of the Mega and the Due, you can easily adapt your custom made shields to the Giga R1 WiFi (remember this board works at 3.3 V though!). Also, additional headers have been added so that the total number of GPIO pins is now 76, and two new pins have been added: a VRTC so you can connect a battery to keep the RTC running while the board is off and an OFF pin so you can shut down the board. Connectors The Giga R1 WiFi has extra connectors on board which will facilitate the creation of your project without any extra hardware. This board has: USB-A connector suitable for hosting USB sticks, other mass storage devices and HID devices such as keyboard or mouse. 3.5 mm input-output jack connected to DAC0, DAC1 and A7. USB-C to power and program the board, as well as simulate an HID device such as mouse or keyboard. Jtag connector, 2x5 1.27 mm. 20-pin Arducam camera connector. Higher voltage support: In comparison with its predecessors that support up to 12 V, the Giga R1 WiFi can handle a range of 6 to 24 V.

The Dragino LDS02 is powered by 2x AAA batteries and targets long-time use, these two batteries can provide about 16,000~70,000 uplink packets. After the batteries run out, the user can easily open the enclosure and replace them with 2 common AAA batteries. It will send periodically data every day as well as for each door open/close action. It also counts the door open times and calculates the last door open duration. The user can also disable the uplink for each open/close event, instead, the device can count each open event and uplink periodically. It also has the open alarm feature, the user can set this feature so the device will send an alarm if the door has been open for a certain time. Each LDS02 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to the LoRaWAN server and it will auto-connect after power on. Features LoRaWAN v1.0.3 Class A SX1262 LoRa Core Door Open/Close detect 2 x AAA LR03 Batteries Door open/close statistics AT Commands to change parameters Uplink on periodically and open/close action Open duration alarm Downlink to change configure Applications Wireless Alarm and Security Systems Home and Building Automation Industrial Monitoring and Control

Pull Down Lever For Highest Score! This Elektor Circuit Classic from 1984 shows a playful application of CMOS 400x series logic ICs in combination with LEDs, a highly popular combination at the time. The project imitates a spinning-digit type slot machine. The Game To play the game, first agree on the number of rounds. Player 1 actuates the switch lever as long as desired and releases it. The LEDs then show the score which is the sum of the 50-20-10-5 digits lit up. If the Play Again! LED lights, Player 1 has another, “free” round. If not, it’s Player 2’s turn. The players keep tab of their scores, and the highest score wins. Features LEDs Indicate Score Multi-Player and Play Again!
