Hardware Description
Overview
Physical Features
Supplied with this kit is a single-frequency UHF RF transmitter, operating on 315, 433.92, 868.3, or 915
MHz. It employs the Atmel T575x series of UHF transmitter ICs and the Atmel AVR
microcontroller IC.
The transmitter is housed in a 2-button key fob with openings in the fob that expose two LED activity-
indicators, a CdS photocell, and a 6-pin header for microcontroller programming (see
Figure 5-1.
Button Inputs: The STK511 transmitter features two push-button inputs. As described in the Software
section, the functionality of these buttons is user-programmable. The transmitter software accompanying
this kit demonstrates both single-button and simultaneous two-button presses.
Indicator LEDs: Two LEDs, located above the buttons, confirm button-press action and indicate the soft-
ware-controlled activity of the T575x transmitter IC.
CdS Photocell: To demonstrate the capability of the 10-bit A/D converter (ADC) resident in the ATtiny13,
this photocell presents to the ADC input an analog voltage inversely proportional to the intensity of the
incident light.
Six-pin ISP Header: The transmitter’s ATtiny13 microcontroller can be programmed through the conve-
nient 6-pin ISP header with the cable supplied in the STK500.
functions. This also allows the user to customize the functionality of the transmitter without having to dis-
assemble the transmitter in order to gain access to the microcontroller (see
