Model - ILLISSI-M4B01 (code - CHI0010).
Top side of the board.
Designed for prototyping products on PIC controllers. Number of legs 28, 16, 8. In SOIC-8, SOIC-16, SOIC-28 cases.
For 28 controller, you can install a reset circuit, and also install a ceramic resonator
MURATA.
Possibility to install three operational amplifiers or PIC10 controllers in the SOT-23-6 package.
Additionally, you can install tact buttons. Between the buttons there is an option of installing a damping resistor and a LED in the 0805 case.
Additionally, you can install 7 transistors and a microcircuit in a SOIC-16 package (for example, ULN2803).
Bottom side of the board.
On the underside there is a possibility to install a MINI-USB connector and a power connector. On the bottom side, you can mount a power supply regulator for a board, type 1117 in a SOT223 or DPAK package. Power from the power connector is supplied through a Schottky diode (to protect the stabilizer from erroneous power connections). Three ceramic capacitors for the power supply filter. After the stabilizer, it is possible to install an electrolytic capacitor. The power supply is designed to be connected from a step-down adapter with an output voltage of up to 16 volts. Recommended for use in prototyping adapters with a voltage of 9 volts.
On the underside are a series of resistors, which in turn are connected to the elements on the top board. For example, the top row of resistors is connected to the base and collector of the transistors, this will make it possible to simplify the use of bipolar or field effect transistors on the board.
For the PIC controller (28-pin), a reset circuit and the ability to install a ceramic resonator are fully assembled.
Additional resistors located under the SOT23-6 places allow the use of not only PIC10 controllers, but also Microchip operational amplifiers in these places. Connecting resistors allows you to simplify the connection of gain setting resistors.
