TinyCircuits Tinyduino Processor board (HCTICI0001, 2, & 24)
See our Tiny Circuits Range Here.
The TinyCircuits TinyDuino is an Arduino compatible board in an ultra compact package. Imagine the possibilities of having the full power of an Arduino Uno in a size less than a quarter! The TinyDuino processor board is roughly equivalent to the Arduino Uno board – same processor, same signals brought out to a shield connector. In fact, most Arduino sketches will work as is without any changes.
Each module in the TinyDuino family has been optimized to include only the core circuits for it’s specific function to keep the size as low as possible at the best possible price. The main TinyDuino processor board includes the core processor circuitry, however the USB and DC power regulators have been offloaded to TinyShields. So for example, if you have a project that doesn’t need support for DC power above 5 volts, you don’t need to include the Power TinyShield, saving you money and keep the overall size down. Or if you don’t need USB on your project, you’d only need one USB TinyShield that you’d use to program your boardsVersions:
HCTICI0001 - TinyDuino Processor Board (ASM2001-R) Rectangular without battery holder.
HCTICI0002 - TinyDuino Processor Board (ASM2001-R-B) Rectangular with CR1632 battery holder
HCTICI0024 - TinyDuino Processor Board (ASM2001-R-L) Rectangular with Lithium battery support.Note: To program this board, you need to use the TinyShield USB Board. See item HCTICI0003.Includes:
Atmega328P processor (same as is used on the Arduino Uno)
8MHz ceramic resonator
Optional battery connector for CR1612-CR1632 coin cell batteries
Optional better connector for Lithium battery (HCTICI0029)
External power supported with a 0.1″ power connection holes
Supports automatic switching between +5V and VBATT (if +5V is present, it will be used instead of the battery)Notes:To program this board, you need to use the TinyShield USB & ICP Board (See HCTICI0003). When used with the Arduino development enviroment you will need to select 'Arduino Pro or Pro Mini (3.3V, 8MHz)' for the board type. Remember, the TinyDuino is 8MHz, not 16MHz!
This board does not include a voltage regulator – do not supply more than +5.5V to VBATT or the +5V signal or you will permanently damage the board and ruin your day.TinyDuino Shield Compatibility Matrix:
If the block is green, the two TinyShields can be used together on the same stack with no issues
If the block is orange, then see the note below for the special conditions
If the block is red, the two boards cannot be used together.
Note 1: Two Bluetooth LE Modules can be used, however one must have the hardware resistors changed to use pins 0 and 1 for the UART
Note 2: Motor 1 cannot be used with a Bluetooth LE Rev 2 board, unless the hardware resistors are changed to use pins 0 and 1 for the UART
Note 3: Motor 1 and Motor 4 channels cannot be used with the WiFi or Nordic BLE TinyShields
Note 4: Only Motor 1 channel can be used at the same time as the 16 and Circle Edge LED TinyShield
Note 5: Multiple Edge LED boards can be plugged together, however they will all show the exact same pattern
Note 6: 9 Axis I2C address must be changed using the address resistors
Note 7: Two TinyShields can be used at the same time if the address resistors are changed on one of the boards
Note 8: The Bluetooth LE TinyShield must have the hardware resistors changed to use pins 0 and 1 for the UART
Note 9: Only Motor 3 & 4 channels can be used with the Audio TinyShield is used
Note 10: Nordic BLE board requires the interrupt resistor to be switched to R3 position
Note 11: Motor 1 and Motor 3 channels cannot be used with the SI4432 433 MHz TinyShield
Note 12: TinyScreen I2C address must be changed using the address resistorSchematic:
