  • Flora Mainboard

    Flora Mainboard

    FLORA has a small but easy to use onboard reset button to reboot the system. The power supply is designed to be flexible and easy to use. There is an onboard polarized 2 JST battery connector with protection schottky diode for use with external battery packs from 3.5v to 16v DC in. Can be used with LiIon/LiPoly, LiFe, alkaline or rechargeable NiMh/NiCad batteries of any size. The FLORA does not have a LiPo charger included by design, this allows safe use with multiple battery types and reduces risk of fire as it is not recommended to charge these batteries on fabric.

  • LM248D

    LM248D

    The LM248 and LM348 quad operational amplifiers, manufactured by STMicroelectronics, incorporate four independent, high-gain internally-compensated, low-power operational amplifiers designed to provide identical functional characteristics to those of the renowned UA741 operational amplifier. These components stand out for their low supply current of 0.53 mA per amplifier and class AB output stage, ensuring no crossover distortion, which makes them highly suitable for applications demanding multiple UA741 type amplifiers and where amplifier matching or high packaging density is required. Furthermore, the LM248 and LM348 offer superior features such as low input offset voltage (1 mV), low input bias current (30 nA), and a gain bandwidth product of 1.3 MHz. They also boast excellent isolation between amplifiers (120 dB) and overload protection for inputs and outputs, enhancing their reliability and performance in various operational environments. The operational temperature ranges are from -40 °C to 105 °C for the LM248 and 0 °C to 70 °C for the LM348, catering to a broad spectrum of industrial applications. Additionally, these components are pin-compatible with LM124, LM224, LM324, further extending their applicability in electronic circuit designs.
