Parts list for standard configurationThe table below illustrates the parts needed to populate the LCDuino-1 board. This list does not include the power supply, wires, hardware or enclosure-related items. For parts not offered by AMB audio shop, Mouser, Digi-Key, Newark, Farnell, RS Components stock numbers for the recommended parts are listed below for your convenience. Additional alternative parts are listed in the Parts selection guide section below.
Some parts are optional, if they are not populated then certain features will either be disabled or degraded. While it is recommended that you install all parts for maximum functionality, you should look carefully at the notes below to find the combination of features that best fits your needs.
Parts selection guideThe following is a list of recommendations and options. Please read through this carefully before you order any parts.
ResistorsAll resistors are miniature through-hole axial-lead types with a body length no longer than about 4mm and no wider than 1.9mm. Carbon film, thin film or metal film types are acceptable, with 5% tolerances or less.
PotentiometersVR1: 100KΩ multi-turn cermet trimpot
CapacitorsC1: aluminum electrolytic capacitor 100µF 6.3V, radial lead, lead spacing: 2.5mm;, diameter: 6.3mm, height: 9mm maximum
Crystals and resonatorsX1: ceramic resonator 16MHz, radial 3-pins, lead-spacing 2.5mm inline
LEDsT-1 (3mm) LED with tinted/diffused lens (wide range of choices). The recommended colors are shown as follows.
Switches & relays
ConnectorsNote: Some additional connectors not listed in the parts list above are needed for γ3. Please see the γ3 website for details.
USB interface cable
Display moduleLCDuino-1 currently supports the following 2x16 (two rows, 16 characters wide), 80mm x 36mm low-power LCD character displays with parallel interface, transmissive or transflective, with a wide selection of colors for the characters and the background:
Infrared remote controlLCDuino-1 is compatible with many hand-held IR remote controls such as those that come with DVD players, VCRs, or televisions. You may also use a universal remote control. The only requirement is that the remote control transmits with 38KHz carrier frequency, and that it uses the standard Sony, NEC, or Philips (RC5 and RC6) protocol. Many other brands also communicate in one of these protocols.
It's likely you would not need to buy a new remote control for use with LCDuino-1. You can re-use the one from an old, retired audio or video component.
If your audio system has other components with IR remote controls, then you should not use those same remote controls for your LCDuino-1. This is to avoid any ambiguity which component you would be commanding. If you use a universal remote control, set it up so that it transmits as a different brand or type of equipment for the LCDuino-1 than for the other components.
In addition, the remote control for your LCDuino-1 should have at least 23 keys in order to support all the features as shown below:
Note: NEC-protocol remote controls are supported, but they sometimes misbehave if a key is pressed too soon after another one. LCDuino-1 may not respond to the key and it needs to be pressed again, or it causes the wrong command to be sent (as if a different key was pressed). This quirk is most often seen with the arrow keys but could happen with other keys. The workaround is to wait a moment between each key-press, or use a remote control with a different brand-protocol. This issue may or may not be fixed in a later firmware release.
