BBox 2

BBox 2 teaches you how to use integrated circuits like timers, comparators, op-amps, counters, logic gates, etc. and we use these to build 20 different projects including a stereo Bluetooth speaker system with a VU meter.


It comprises of 20 different kits that are made up of a PCB, all the necessary through-hole components and also a short description of the circuit operation along with the schematic. It contains over 400 items and the PCBs help you practice your soldering skills too.

Component Information

We take a practical approach in learning how to use different integrated circuits ranging from the simple 555 timer IC to a CSR8645 Bluetooth audio receiver.

Project Kits

BBox 2 contains all the components needed to build the kits along with a reference sheet to help you understand the circuit operation.


Here’s a list of the supporting material that will help you get started with BBox 2. Use this as a starting point along with the reference sheets present in BBox 2.
