A small board which breaks out the lower end LTC2450 16 bit ADC from Linear Technology. This ADC has 1 single ended input and an SPI output. Its max sample rate is only 30sps, however it is very easy to use for the occasional simple conversion. The low pass filter on the input (R0 and C0) has a cutoff frequency of ~1.5KHz as prescribed by the data sheet. These values can be changed if needed.

Power: Vcc = 2.7V to 5.5V

Input : Vin = -0.3V to (Vcc + 0.3V)

GND, CS, SDO and SCK: self explanitory

Parts

U0: LTC2450CDC-1#TRMPBFCT-ND (DigiKey)

C0, C1: 0.1uF Ceramic 0603 Cap

C2: 10uf Ceramic 1206 Cap

R0: 1K 0603 Resistor

Headers: Generic 0.1" Pitch

Small adapter board for use with the Open Panzer Tank Control Board (TCB). On one end of the board you solder the leads from a 3-pin JST-XH pigtail, on the other end a right-angle Molex Micro-Latch connector. This allows Tamiya mechanical recoil units to be completely plug-and-play with the TCB.

See the Accessories page of the Open Panzer TCB wiki for more information.

A small board used to easily limit current in standard RC LED strings that use JST-PH connectors.

You can choose to use a standard ¼ watt through-hole resistor of any value, or a current-limiting IC such as the Diodes Inc AL5809 (typical choices might be 20mA or 40mA).

Use a JST-PH pigtail for the voltage input, and plug it into your light controller. Search eBay for “JST PH 2 pin connector.”

For the output you can use a right-angle JST-PH connector (JST Part No.
S2B-PH-K-S), or you can use the large solder pads on both the top and bottom of the board to solder LEDs or wire directly to the board.

The bottom of the board is entirely white silkscreen for writing a small note with a fine-tipped Sharpie - such as the resistor value, so you don’t forget.

Use clear heatshrink when done assembling. Heatshrink that is approximately ¾" (18-20mm) wide when laid flat works well.

See the Accessories page of the Open Panzer TCB wiki for some photos, or this post on the Open Source RC Lights thread.
