ART6212 Product Specification
12 mm x 12 mm x 2.4 mm
Description
Amp’ed RF Tech presents the ART621 Wi-Fi &
BLE combo module: 802.11abgn/BLEv4.1. The
ART6212 is a small footprint low cost RF module
intended to help customers shorten product
development cycles and reduce cost.
Fully compatible with our AmpedUP embedded
protocol stack, the ART6212 may be matched
with many Host MCU chipsets. Additionally,
Linux and Android OS drivers are available.
The ART6212 is offered in WiFi/BLE combo,
WiFi only, and BLE only configurations.

2. Hardware Design
• All unused pins should be left floating; do not ground.
• All GND pins must be well groun ded.
• Traces should not be routed underneath the module.
2.1. Module Reflow Installation
The ART6212 is a surfac e mount Bluetooth m odule supplie d on a 44 pin, 6-la yer PCB. The final assem bly
recommended reflow profiles are:
For RoHS/Pb-free applications, Sn96.5/Ag3.0/Cu0.5 solder is recommended.
• Maximum peak temperature of 230° - 240°C (below 250°C).
• Maximum rise and fall slope after liquidous of < 2°C/second.
• Maximum rise and fall slope after liquidous of < 3°C/second.
• Maximum time at liquidous of 40 – 80 seconds.

4.1. WL_ REG_ON & BT_RST_N
These pins are alwa ys an input pins, acti ve low, with a PD dur ing res et. This s ignal MU ST be active dur ing
power sup pl ies i nit ia liza tio n and, w he n a ll po wer s u ppl i es ar e s tab le, it must rem ain ac tive lo w for at leas t 2
cycles of the slow clock in order to insure good reset functionality.
When WL_REG_ON is low, the WIFI chip is power down.
When BT_RST_N is low, the WIFI chip is power down.

4.2. UART and SPI interface
UART_CTS is an input with PU, UART_RXD is an input with PU, UART_TXD toggles from input PU to output
High and UART_RTS toggles from input PU to output Low 70ms after reset, enabling UART communication
if needed.
