SPARK AMPLIFIER HOW TO

This voltage should be designed with a minimum of 100mV below VSUP voltage.' The output voltage is equal to VAVDD=VBG*(R1+R2)/ R1 (Fig. There is a statement: 'When using internal analog supply regulator, the dropout voltage of the regulator depends on the external transistor used. So there is no reason why you can't use single 3.3 V supply for both VCC and VDD with this board. If you read the HX711 data sheet, you'll see that it specs a range of 2.7 V to 5.5 V for DVDD and VSUP. Note: Special thanks to Bodge for supplying the Library for the HX711! Please keep in mind that some load cells might have slight variations in color coding. The YLW pin acts as an optional input that is not hooked up to the strain gauge but is utilized to ground and shield against outside EMI (electromagnetic interference). Each color corresponds to the conventional color coding of load cells: These are commonly colored RED, BLK, WHT, GRN and YLW. Load cells use a four-wire Wheatstone bridge configuration to connect to the HX711. Check the hookup guide below for more information. Any microcontroller’s GPIO pins should work, and numerous libraries have been written, making it easy to read data from the HX711. The HX711 uses a two-wire interface (Clock and Data) for communication. It has all the features of the HX711 but with additional library support, a true I2C interface, and no soldering required! Need even more? Checkout the SparkFun Qwiic Scale. This version of the SparkFun Load Cell Amplifier features a few changes that you specifically asked for! We have separated the analog and digital supply, as well as added a 3.3uH inductor and a 0.1uF filter capacitor for digital supply. This can be handy for creating your own industrial scale, process control or simple presence detection. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration you’ll be able to get very accurate weight measurements. The Spark Mini will allow you to record yourself as it can be used as an USB audio interface.The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. Charging time will required up to 3 hours.

Battery is a built-in Lithium rechargeable battery delivering up to 8 hours of play time (on mid volume). On the Spec sheet, we get a 10 Watt Class D amplifier and two 2″ Custom designed speakers. The Spark Mini is a battery-powered practice amp and Bluetooth® speaker including smart app integration which should offer similar features as the ones offered for its big brother, the Spark amp. The wait is now over as Positive Grid just announced the release of a Spark Mini! What’s the Spark Mini ? One would have expected a bigger amp or a Spark MKII. They have been teasing for the past couple days about something BIG to arrive on ( Read 2/22/22 in the US date format).

We get a lot of requests on the Spark Amp Lovers Facebook group about how to plug an external cab to the Spark to get a bigger sound, so I must say I am a bit surprised by Positive Grid last annoucement.
