206
207 1. Change R14 to 1M ohm
208 1. Change R3, R4 to 4.7Kohm. So no need to modify them for 3 DS18B20 connection.
209 1. Add ESD to each I/O
210
211 **LSN50 v2.0:**
212
213 * Change to a new enclosure. Improve with external antenna, IP68, ear hook.
214
215 **LSN50 v1.3**:
216
217 * Add P-MOS to control 5V output
218
219 **LSN50 v1.2**:
220
221 * Add LED. Turn on for every LoRa transmit
222 * Add pin PA4, PB13, NRST
