Our engineers open up popular gadgets, development boards and modules to show what is inside: the components, the circuit design and how it all works together. Each teardown covers the parts used, the schematic where it can be traced, and what designers can learn from it.
Bluetooth trackers like Apple AirTags and Samsung SmartTag are a convenient way to locate misplaced items nearby, but their dependence on nearby smartphones limits their usefulness over long distances. Cellular GPS trackers overcome this limitation by communicating directly over the mobile network, allowing them to report their location from anywhere with network…
This is the teardown tutorial of ESP32-2424S012C, an ESP32 C3-based development board with an integrated display. This device comes in very handy, as it has our favourite ESP32-C3 onboard, a 1.28” IPS Capacitive Touch Screen display with a 240×240 px resolution. The coolest thing about this is that it can be custom-programmed to our specifications using a wide range…
Model Name: FNIRSI-1014DAbstract :An oscilloscope that retails at INR 13K basically covers all of the hands-on subjects a 4-year engineering syllabus teaches in theory. The only issue is that none of this is practiced. We barely get past MCUs hands-on.This…
The E88 quadcopter drone is a consumer-grade quadcopter drone designed for indoor and outdoor recreational flying. Featuring a foldable design, a WiFi camera, and altitude-hold capabilities, this detailed E88 drone teardown represents a typical entry-level drone in the sub-₹2000 market segment. The drone's compact…
In this article, we will be learning about the features and working of a 3S 6A lithium Battery Management System or BMS along with checking out the components and the circuitry of this module. Furthermore, we have done complete reverse engineering of the module by removing all the components from the PCB and measuring all the PCB traces with the multimeter. For…
This comprehensive BMS circuit diagram guide explains the features and working of a 4S 40A Battery Management System (BMS) commonly used with 18650 Li-ion cells. We'll explore the complete BMS circuit for lithium-ion battery applications, including detailed schematics, component analysis, and protection mechanisms. This lithium battery BMS circuit diagram breakdown includes…
