GPT(General purpose timer) A 32‐bit counter with programmable clock divider and pre‐scalar Input capture for external inputs Edge‐aligned and Center‐aligned PWM ADC The ADC module has a programmable resolution from 10 to 16 bits. Flexible gain buffer setting of 2x, 1x, 0.5x Highest throughput rate with 10‐bit resolution is 250ksample/s UART UART0 for debug; UART2 used to communicate with other device. I2C Three speeds: standard mode(100kb/s), fast mode(400kb/s), high‐speed mode(3.4Mb/s) Clock synchronization Master or slave I2C operation, multi‐master, multi‐slave operation, and arbitration support JTAG Just for firmware burning Antenna When customer selects the on‐board chip antenna, the antenna must away from metal or high components at least 15mm, and do not put any components or copper under the antenna, it also can not be shielded by any meal enclosure. As the simulation result show, the pcb antenna has 1.5dB gain and its S11<‐14dB between 2.4GHz~2.5GHz The device also supports external antenna. The parameters required are as followed: Frequency range 2.4G~2.5G Impedance 50Ohm VSWR <2 Return loss <‐10dB Connector type IPEX Warning 1. This device complies with part 15 of the FCC Rules.
