In the realm of portable power, USB battery banks reign supreme, providing a lifeline to our tech-dependent lives. But what if you could know more about your battery bank’s inner workings? What if you could peer into its soul and understand its battery life, charging status, and output current? Well, buckle up, folks, because we’re about to embark on a journey to unlock the secrets of USB battery banks.
Unveiling the Enigma: Why Telemetry Matters
Most USB battery banks are like enigmatic oracles, providing only cryptic LED indicators for battery life. But for those who seek deeper insights, telemetry is the key. Telemetry, the art of gathering data from remote sources, can reveal a wealth of information about your battery bank’s health and performance.
The Holy Grail: Battery Voltage and Beyond
Among the telemetry treasures, battery voltage stands as the holy grail. This precious data point unveils the remaining battery life, allowing you to make informed decisions about when to recharge. But that’s not all; telemetry can also shed light on charging and output currents, empowering you to optimize your charging strategy and ensure your devices receive the power they crave.
The Chosen One: Keenan Johnson’s Quest for Telemetry
Enter Keenan Johnson, a fearless adventurer in the realm of electronics. Faced with an upcoming project that demanded intimate knowledge of a USB battery bank’s telemetry, Johnson embarked on a quest to extract this hidden knowledge. His weapon of choice? A MKR WiFi 1010 board, an ADC module, and a dash of programming prowess.
The Hidden Gateway: Unlocking the Battery Bank’s Secrets
Within the battery bank’s unassuming exterior, Johnson discovered a treasure trove of test points, labeled P+, LOAD, and CHRG. These portals held the keys to unlocking the battery voltage, output current, and charging current, respectively. With the MKR WiFi 1010 board and ADC module acting as his trusty companions, Johnson connected to these test points, transforming raw data into actionable insights.
The Revelation: A Symphony of Telemetry
Through the magic of programming, Johnson conjured a user-friendly interface, granting remote access to the battery voltage, load current, and charge current. Like a conductor leading an orchestra, Johnson orchestrated these data streams into a harmonious symphony of telemetry. And to add a touch of visual flair, an Adafruit NeoPixel LED status indicator illuminated the scene, providing a visual representation of the battery bank’s status.
Bonus: Telemetry, the unsung hero of the electronics world, has the power to transform mundane devices into vessels of knowledge. Embrace its potential, and you too can unlock the secrets of your electronic companions.
In conclusion, USB battery banks are no longer mere power sources; they are gateways to a world of telemetry insights. With the right tools and a dash of ingenuity, you can unveil their hidden secrets, optimizing your charging strategy and ensuring your devices never run out of juice.
