Our company specializes in developing compact devices for embedded systems. Typically, we handle these projects internally, but in this instance, we’re short on time for an in-house project. Therefore, we require an additional resource that may also be engaged in the future if successful.

We need an ultra-compact device with a 12-millimeter diameter, composed of two boards with an LIR1025 battery sandwiched between them. The boards should include:

    nRF52840 with a Bluetooth antenna
    An accelerometer capable of reading acceleration by the processor and (crucially) awakening the processor from deep sleep upon motion detection
    A temperature sensor (preferred)
    A compact connector with lines for SWD, battery power/charging, USB. Compliance with standards like USB type C is not necessary
    Power circuitry for LIR1025
    Two RGB LEDs, one on each board
    The boards should be interconnected with headers or connectors, without the need for soldering
    The device should have a round (cylindrical) form factor with a 12 mm diameter and a height not exceeding 12 mm
    Prototypes will be manufactured by JLCPCB and must adhere to their manufacturing capabilities and available components.
    The cost of prototypes should be reasonable, though price optimization is not a priority.
    Development time is critical.
    Deliverables should include:
    Source files in Altium Designer or K-CAD in the client’s git repository
    A complete file set for ordering samples from JLCPCB
    This task is challenging, so please undertake it only if it’s within your capabilities. Unsuccessful attempts will not be compensated or appreciated.

Budget: $1,500
