SinoVoip’s Linux-friendly, 60 x 30mm Banana Pi M2 Zero (BPI-M2 Zero) SBC closely mimics the Raspberry Pi Zero W, but has a faster Allwinner H2+.

We have today started work on our next module, the Accra counter module. The hardware is already done. This unit will be able to count pulses on four channels and also measure frequency on each channel. It can have alarms set for going over a counter level or when counting down to zero and for a frequency that is outside of a specified frequency range.
It has a built-in linear calculation algorithm that can translate pulse to real world measurement units. This can for example be used for utility meter measurements and gives the correct measurement value sent out on the VSCP bus.
Kilafors will be supplied later as an add on modules to detect S0 (IR) pulses so that Accra can be hooked on to an electrical meter and output power usage data.
This will be the seventh module in the CAN4VSCP series and will be followed by Vilnius for 12-bit A/D measurements.
The module has ten 5V channels that individually can be set to either an input or an output.
Each output can have a pulse automatically generated.
Each channel can have a protection timer associated with it which turns it off after a specified time. This can be used as a security feature so that a critical controlled resource is not kept on when a communication line has been lost but can be used to keep an output on for a specific time for other uses.
Alarm events can be generated when a pin change state. Perfect for alarm setups.
State of inputs/outputs can be streamed with configurable time interval.
Inputs can be used as button inputs with repeat.
The Beijing module have a decision matrix with eight entries that can set a pin high or low, toggle a pin, send status for a pin or all pins, or turn on/off pulse on a pin. This makes it easy to construct autonomous systems.
The module can be wall mounted or attached to a DIN rail as all modules in the CAN4VSCP series from Paradise of the Frog.
