CC3235MODSF LaunchPad™ Development Kit (LAUNCHCC3235MOD)
1.2 LAUNCHCC3235MOD Key Features
The LAUNCHCC3235MOD SimpleLink LaunchPad includes the following features:
• CC3235MODSF, SimpleLink
TM
Dual-Band Wi-Fi
®
module solution
– Integrated MCU
– 40.0-MHz Crystal
– 32.768-kHz Crystal (RTC)
– 32-Mbit SPI Serial Flash
– RF and Full Power-Management Components
• 40-pin LaunchPad standard that leverages the BoosterPack ecosystem
• TI standard, XDS110-based JTAG emulation with serial port for flash programming
• Supports 4-wire JTAG and 2-wire SWD
• Two buttons and one RGB LED for user interaction
• Back-channel universal asynchronous receiver/transmitter (UART) through USB to PC
• Onboard chip antenna with U.FL for conducted testing selectable using 0-Ω resistors
• Onboard accelerometer and temperature sensor for out-of-box demo with option to isolate the sensors
from the inter-integrated circuit (I
2
C) bus
• Micro-USB connector for power and debug connections
• Headers for current measurement and external JTAG connection (option to use the onboard XDS110
to debug customer platforms)
• Bus-powered device with no external power required for Wi-Fi
